Colorful snail shells on display at the West Coast Shell Show.
On Sunday I peered into Balboa Park’s Casa del Prado and discovered a surprising exhibition open free to the public. It was the San Diego Shell Club’s amazing West Coast Shell Show!
There were so many beautiful shells covering table after table it blew my mind. Every shell, I noted, was unique and interesting, and many that I saw seemed like exquisite works of art. Nature’s abundant beauty was spread throughout the room. It seemed I had blundered into a vast treasure of spilled jewels.
When I walk along a beach, I like to search the sand for bright or colorful objects washed up by the tide. But I honestly know next to nothing about shells from molluscs on land or in the sea. So I learned a few fascinating facts during my short conversations with a friendly hobbyist and a dealer.
Among other things, I learned some shells are highly prized for their rarity and apparent perfection, and that a few can fetch many thousands of dollars. I also learned there are relatively few serious shell collectors worldwide. But those who have a passion for shells have a hobby that promises new discoveries at every turn and inexhaustible wonder.
The West Coast Shell Show was presented in Balboa Park by the San Diego Shell Club.Beautiful shells of all types could be enjoyed–and purchased–inside the Casa del Prado over the weekend.A variety of different colored abalone shells were on display at the show.A wide variety of beautiful cowries. They almost look like polished agates to me. The cowry is a type of sea snail.The Story of Shells appears to have many chapters and pages.The shells seemed like exotic jewelry or small works of art, no two exactly alike.One display case showed a large collection of fantastic chitons. To me these almost look like varnished wood!Dr. Wesley M. Farmer had a table full of scientific books, plus lots of unique art he’d created concerning nudibranchs, a type of sea slug. They shed their shells after their larval stage.All sorts of fascinating mollusc art created by Wes Farmer, including specimens made with colored oven bake clay.The public could enjoy many fantastic displays at the West Coast Shell Show!

A mushroom fair was held this weekend in Balboa Park inside the Casa del Prado. The event was put on by the San Diego Mycological Society.
There’s a fungus among us! I’m not kidding! Â (Groan.)
All sorts of mushrooms were on display inside Balboa Park’s Casa del Prado today during a special show by the San Diego Mycological Society.
I wandered through this cool “mushroom fair” and took a good look around. And I learned quite a lot!
Check out a few fun photos and some informative captions…
Mushroom enthusiasts check out all sorts of displays at the mushroom show. Mushroom facts, art, and food products like jerky were plentiful.Several tables exhibited different types of mushrooms one might encounter in nature. The San Diego Mycological Society puts the fun in fungus!These mushrooms are all edible. Some are said to taste better than others.A basket full of Bolbitius vitellinus. Labelled edible but mediocre. According to Wikipedia, it’s inedible. I’m no expert, so don’t ask me.Cooking with Wild Mushrooms. (Click image to enlarge the sign for easy reading.)Okay, these are definitely poisonous! Children were advised not to touch. I steered well clear!Here’s a monster yeast fungus so villainous that Captain Marvel had a tough time coping with it.I do know that much of the art displayed at the mushroom show was tasty!Check out this fascinating poster and the following photo. Spore prints show how spores are ejected from the mushroom gills.These spore prints strangely remind me of human thumbprints.An inventive artist created some spore print cards, hand made from mushrooms found in San Diego! Cool!Volunteers from the San Diego Mycological Society are collecting mushroom specimens found throughout the county. Tiny tissue samples will be scientifically barcoded for species identification.All sorts of arts and crafts, books and fascinating stuff was for sale at the mushroom fair.Colorful mushroom ornaments!
UPDATE!
I swung by the annual event again in 2018. I saw many of the same interesting exhibits, and snapped a couple more fun pics…

Photo of exterior of the Salk Institute for Biological Studies in La Jolla. The famous building was designed by renowned modernist architect Louis Kahn.
One of the world’s most famous works of modern architecture is located in San Diego. Â I’m referring to the Salk Institute building in La Jolla. Its designer was Louis Kahn, considered to have been one of the most important, innovative architects of the 20th century.
An exhibition now running at the San Diego Museum of Art takes a thorough look at the remarkable life, work and genius of Louis Kahn.
Last weekend I was given a personal tour of the amazing exhibit and found myself completely blown away by its scope. The photos, films, sketches, notes and architectural models, including a life-size portion of an extraordinary house–even works of art produced by Louis Kahn himself– were too much for my mind to absorb in one visit.
Kahn was undoubtedly a genius. His unique modern structures seem like ancient timeless monuments, made beautifully functional. They are simultaneously complex and simple. They are geometric, symmetric, modular, clean. They seem solid but light-filled. They contain unusual surprises of line, curve and angle. They are iconic.
Louis Kahn had a long, prolific career. Â His work can be found throughout the world, and includes the enormous, citadel-like National Assembly Building of Bangladesh. Some of his more famous creations in the United States include the Kimball Art Museum, the Yale University Art Gallery, the library at Philips Exeter Academy, the Norman Fisher House in Philadelphia, the Franklin D. Roosevelt Four Freedoms Park, and, of course, San Diego’s own remarkable Salk Institute.
There is so much to see in this impressive exhibit–there were so many amazing designs produced by Kahn during his productive lifetime–that I can’t begin to cover it all in this blog. So I must direct you to the San Diego Museum of Art’s website. To get a small hint of what you will discover at the museum, you might want to check out the Wikipedia article on Louis Kahn.
This weekend I headed up to La Jolla to see if I could snap some good photos of Louis Kahn’s very famous Salk Institute building. Walking around, I managed to photograph the exterior, but I was unable to access the interior courtyard. So I’ve included one photo from Wikimedia Commons, just to provide a quick idea. Peering through a fence, I did glimpse some scaffolding in the interior area, so I suppose that would have nullified my photographic attempts, anyway.
The Salk Institute building’s walls are made of smooth exposed concrete. While this material might appear stark, the monumental appearance, the intriguing shapes and architectural symmetry are absolutely impressive. There is a mathematical, complex interaction between shadow and light that is difficult to describe–and quite beautiful.
Want to see more of Kahn’s brilliant work? Head over to the San Diego Museum of Art in Balboa Park before this special exhibition closes on January 31, 2017.

Scripps Institution of Oceanography’s new Research Vessel Sally Ride welcomes the public at San Diego’s Broadway Pier.
If you love science, technology and the study of our planet’s oceans, please enjoy the following photo tour of a very special ship. In this blog post we will visit the newest, most highly advanced oceanographic research ship in the world!
The world-famous Scripps Institution of Oceanography, a part of UC San Diego located in La Jolla, debuted their new research vessel Sally Ride this weekend at the Broadway Pier. Today the public was invited to come aboard and learn about the future work of scientists at sea.
The R/V Sally Ride is equipped with technologically advanced equipment, sensors, labs and computer systems. In the years ahead, it will be tasked with learning about and preserving the oceans, studying and protecting the environment, and inspiring the next generation. Using satellite communication and the scientists aboard, students and teachers throughout the world will actively participate in ocean exploration.
Except in documentary films, the public seldom sees the interior of an ocean-going research vessel. So today was an opportunity not to be missed!
Please read the photo captions where I’ve tried, to the best of my knowledge, to provide accurate details. But I’m no expert. If you’d like to leave a correction or useful information in a comment, please do!
The public was invited to tour the new research ship Sally Ride. It was a rare opportunity to see how high tech exploration is carried out by UCSD Scripps scientists and oceanographers.The free public tours of R/V Sally Ride drew a good crowd on a Sunday in October, 2016. These people smartly arrived an hour early to reserve a time slot.The tour began inside the Port Pavilion on Broadway Pier. Many displays highlighted the work of UCSD’s Scripps Institution of Oceanography.UC San Diego embarks upon a new journey of exploration and boundary breaking with America’s newest research vessel R/V Sally Ride. Sally Ride was the first American woman in space.A large display goes over the history of The Evolution of Climate Change Science. UCSD scientists have made important contributions in this field.People inside the Port Pavilion learn about science and technology related to the understanding of planet Earth’s oceans.These examples of what is found when taking sediment cores on the ocean floor include tiny elegant Radiolaria.The Autonomously Deployed Deep-Ocean Seismic System’s Wave Glider is powered by solar and wave energy. It links with satellites and ocean bottom seismometers to help predict earthquakes and tsunamis.Some advanced visual equipment on display during the public debut of Research Vessel Sally Ride in San Diego.

The big A frame, winch shack, extending crane, and two retractable arms on the starboard side of the ship are visible.Visitors eagerly head up the gangplank to explore America’s newest, most advanced research ship.Here we go!Looking down to our left.This rosette frame can be lowered into the water with a variety of mounted sensors. We’ll see it again in a bit.Heading down steep steps to the research ship’s fantail and work deck.We are halfway down. Many distant sailboats can be seen on San Diego Bay this beautiful but mostly overcast Sunday.R/V Sally Ride is equipped with shops, labs, winches, launch frames, booms and the newest scientific instruments and communication gear. The busy fantail and work deck are where science meets the sea.The gigantic A-Frame at the stern of RV Sally Ride can lift loads up to 30,000 pounds! Wire and cable deploy towed instruments. Moorings and acoustic equipment are also deployed in this manner.Visitors on the rear deck of R/V Sally Ride learn about science on the sea from a crewmember.Looking forward and up, we see several levels to the ship. If I understand correctly, the electronic display indicates a cable’s tension, payout and speed.Turning a bit to the right, we see the big crane atop a staging bay that is sheltered from the weather. Inside, equipment can be carefully prepared before deployment out in the elements.Now we are heading toward the windowed winch shack, along the starboard side of the ship toward the two retractable arms.One of two mechanical arms used to lower sensors, nets, and other oceanographic equipment into the water. They are called LARS, which stands for launch and recovery systems.A member of the public reads a sign explaining that the LARS are controlled from the winch shack. Wire or cable is used to lower equipment overboard.This rosette frame is holding a CTD, or conductivity, temperature and depth sensor. It can be lowered to a depth of nearly 4 miles! Niskin bottles attached to the frame can capture samples to be analyzed on the ship or at a later time.A poster inside the R/V Sally Ride’s staging bay details the ship’s main characteristics.Heading through a watertight door into the Wet Lab. Water samples are brought here for storage and analysis. There are drains in the floor!Another poster contains photos taken during RV Sally Ride’s construction.

A huge spider-like working octopod vehicle on display in the Plaza de Panama at 2016 Maker Faire San Diego!
Check out some cool photos! I took these this morning at 2016 Maker Faire San Diego which is being held this weekend in Balboa Park!
This now annual event–I believe this is the second year–attracts creative people of every type: engineers, inventors, dreamers, artists, students . . . Â If the human imagination can envision it, these folks will build it!
If you are a dreamer and a doer, head down to Balboa Park and be inspired!
Maker Faire San Diego has taken over Balboa Park this weekend. The annual event features fantastic creations and the inspired creators who like building cool stuff!This super cool octopod moves slowly forward and backward using its spider-like feet. I’d love to sit inside and drive it! I learned that it doesn’t steer very well, however.In the morning, before the Maker Faire officially opened, I spotted two cupcake cars heading through Balboa Park!This guy was flying what appeared to be a huge model of a Star Wars Imperial Star Destroyer down Balboa Park’s El Prado!A bunch of Maker Faire exhibitors set up on Saturday morning in front of the San Diego Air and Space Museum in Balboa Park.This human powered submarine was created by a team of students at UCSD. It competed in the International Submarine Race and was propelled by a 3-D printed fin.This cool robot was created by high school students, namely High Tech High’s Top Hat Technicians. It competed in an event where a ball had to be shot at a goal.Make your own molecule using this cardboard Molecube!These awesome guitars were made by students in a special STEM Guitar-Building class at San Diego City College.The Ghostbusters ECTO-1 vehicle has arrived for Maker Faire San Diego, as well as a Jeep from Jurassic Park.Commissioner Gordon must be nearby.

Help us Save the Vaquita display at the east gazebo of Seaport Village in San Diego. The band Insect Surfers was providing some music!
The Vaquita is the world’s most endangered marine mammal. It is thought that about 60 of the animals exist in the ocean today. This small species of porpoise (Phocoena sinus) lives in the warm waters of the eastern Pacific Ocean–specifically in the northern Gulf of California, in a small region east of Baja California not too distant from San Diego. According to the International Union for the Conservation of Nature, the Vaquita is classified as Critically Endangered.
International Save the Vaquita Day was observed today in San Diego and many other cities around the world. I swung by Seaport Village to see what efforts are underway to save Mexico’s “Panda of the Sea” and to learn a little about the Vaquita.
I learned that the Vaquita, thankfully, enjoys clean waters. Their big threat is being entangled in the gillnets of fishermen. A major effort is underway to eliminate these nets from the Vaquita’s natural habitat. But some fishermen, seeking to provide a living for themselves, use them anyway.
I learned there’s also an effort to inform consumers that some shrimp and fish that one finds in the grocery store is caught with gillnets. It is hoped enlightened shoppers will seek out and purchase seafood that isn’t caught with this type of net.
I learned that Vaquitas have never been held in aquariums, and has only been known to science since 1958.
If this species goes extinct, it will be gone forever.
These nice ladies are working hard to save the Vaquita. It is hoped many others will join the effort, in any way possible. Time is very limited–perhaps a year or two–before the species might go extinct.Kids make art and learn about the critically endangered Vaquita, a marine mammal that clings to a tenuous existence not far from San Diego.

Unique holographic artwork painted on glass as seen through a downtown San Diego window. Reflections of life on the street are also visible in this photo.
Look what I discovered! These super cool, revolutionary paintings are on display in downtown San Diego. You’ll find them arranged behind the windows of the now closed Gaslamp 15 movie theater, just beneath the old marquee.
When I read the signs near these vibrant paintings, my curiosity was piqued. An inventive gentleman named Liguori has used proprietary holographic paints to create two-dimensional images that seem three-dimensional. The visual appearance changes depending upon the angle from which the artwork is observed!
According to the written description, this method of painting is so unique that it constitutes a completely new art form! My photos through the glass windows don’t really demonstrate the appearance of three dimensions. But my photos do include interesting reflections from the city street! Melded with the colorful art are buildings, people, a bus, cars, and just regular ordinary stuff a person walking down the sidewalk might observe. In a sense, this adds another unusual dimension! Please read the two signs that I photographed. Especially if you are keenly interested in physics and philosophy, and unbounded human creativity.
Do you have questions? Would you like to learn more? Perhaps you’d like to purchase one of these completely revolutionary pieces, which belong to an art movement yet to be named! That’s what the sign says! And all proceeds go to charity! To contact Liguori, use the email that is at the bottom of the signs.
Very cool!
Very cool works of art are on display in downtown San Diego. You can see them in the windows of the now vacant Gaslamp 15 movie theater, beneath the old marquee.Liguori is a successful businessman in his seventies. He took up painting late in life. He developed a totally new art medium. All the proceeds of his work will go to various charities!More examples of Liguori’s dazzling, thought-provoking pieces. Apparently the application of his special holographic paint on glass is an entirely new, revolutionary art form.Bold color stimulates the human mind and imagination. Like the universe (or perhaps multiverse), what is seen depends on the observer’s momentary point of view.Liguori’s work provides a physical manifestation of objective reality. When viewing this holographic art, countless three dimensional images are possible. It depends upon the angle of observation.Abstract art melds with cars, buildings, and bits of everyday experience in one wonderful window.More fantastic artwork. I was unable to take photographs without reflections in the windows. But it makes these images that more interesting!A dim somebody strides through a splash of vibrant color.The cosmos is incomprehensibly enormous and complex. Different wavelengths, angles, points in space and time…different states of mind and a blink of the eye. Objective reality is observed only in tiny slices.
UPDATE!
I’ve decided to walk past these holographic paintings again, and attempt to take some better photos without the street reflections. I’ll post them shortly…
Okay, I somehow got two close-up photos through the windows that are pretty amazing. Here they are…

Visitors at the San Diego Zoo Centennial Festival in Balboa Park learn how rare, threatened and endangered native plants are being saved by the zoo.
Many know how the San Diego Zoo is a world leader in working to protect animal species from extinction. One important task is to store critical genetic material. Their world-renowned Frozen Zoo has been storing cryogenically preserved biological samples since 1976.
When I walked through the San Diego Zoo Centennial Festival in Balboa Park last Saturday, I learned something that really impressed me. Not only is the zoo striving to save the world’s most endangered wild animals, but San Diego Zoo Global has developed an important native plant seed bank, in an effort to conserve rare and threatened local plant species.
The zoo is member of the California Plant Rescue Partnership, whose goal is the long term conservation of wild plant species through seed banks and field work. One of the people with whom I briefly spoke has the job of hiking about San Diego County, searching for and monitoring populations of these rare plant species. What a fantastic job that must be!
The zoo has developed an extensive seed collection. Some native plants being protected are the San Diego golden star Bloomeria clevelandii, Dudleya brevifolia, Monardella stoneana, Comarostaphylis diversifolia ssp. diversifolia, and Corethrogyne filaginifolia var. linifolia, which is commonly called the Del Mar sand aster.
The San Diego Zoo Institute for Conservation Research is also working hard to save the Tecate Cypress in Southern California and Baja California, a tree that the rare Thorne’s hairstreak butterfly depends upon. A poster at the zoo’s centennial event helped to explain why this effort is so urgent.
San Diego Zoo Global’s Native Plant Seed Bank and horticulture departments have planted 500 Tecate Cypress trees to establish a field gene bank. (Click to enlarge.)The San Diego Zoo’s conservation efforts extend beyond protecting animal species threatened by extinction. Plants are important, too!

A mad scientist at the San Diego Festival of Science and Engineering shows a kid how to have some fun with magnets!
Here are 14 different simple science and engineering projects that kids are sure to love! I’ve included lots of instructions and photographs–courtesy of many exhibitors at this year’s San Diego Festival of Science and Engineering Expo, held yesterday at Petco Park. I also blogged about the event last year.
Check out this fun stuff! Feel free to share! First up . . . how to make slime!
HOW TO MAKE SLIME
Who doesn’t love slime? Slime is fun! And making it is easy! These instructions are courtesy of Vertex Pharmaceuticals, who had a fascinating exhibit at the big STEM education event held at Petco Park.
Just click the image with easy directions to enlarge it! You can enlarge the other images on my blog in the same way, if you want a closer look. Feel free to share these useful how-to photos on Pinterest or with your friends, if you’d like!

HOW TO MAKE A FUN PAPER ROCKET
Follow the diagram to cut and fold a simple paper rocket with paper clip! These instructions are courtesy of the San Diego Air and Space Museum in Balboa Park. Kids love the world-class museum. It’s one of the coolest places in San Diego!
How to make a cool paper rocket, using a rectangular piece of paper, scissors and a paper clip.
HOW TO FOLD AN ORIGAMI BOAT
Look at these instructions on how to fold your very own origami boat! My friends at the Japanese Friendship Garden in Balboa Park provided this information! I even once made one! (And if I can succeed, believe me–anyone can do it!)
How to fold an easy origami boat that really floats!
HOW TO MAKE MATCHBOX ROCKETS THAT REALLY WORK!
Here’s how you can make a tiny rocket that actually works in much the same way as a real solid-fuel rocket. Wrap a single matchstick in a small strip of tin foil, then crimp one end. Look at my photos to get an idea of what to do. Be careful! You know what they say about playing with matches! Have an adult help out!
Oh, I forgot to mention. This cool experiment is courtesy of the Magnolia Science Academy!
How to make matchbox rockets and why they work. This is for older, supervised kids. Fire can be dangerous.Wrap a match in a small strip of aluminum foil.Crimp the match head end of the tube (the rocket’s nose) so exhaust pressure doesn’t escape in that direction.Prepare for lift-off from a clever, fireproof launching platform! Safely apply flame and let fly!
HOW TO MAKE AN “AIRZOOKA” THAT SHOOTS CO2 RINGS!
Here’s another cool project I discovered at the Magnolia Science Academy booth. A student had created a simple “Airzooka” that shoots perfect white cloudy rings of carbon dioxide!
The trashcan with a hole part looks easy. To create the membrane that launches the CO2 rings, you’ll need to use a somewhat flexible material, like a plastic sheet. Once the can is filled with gas, just slap it with your hand and out comes a “smoke ring”!
How to make an “airzooka” using a plastic trashcan with a hole at one end and a pliable membrane on the other. Fill with carbon dioxide gas and shoot white rings by hitting the membrane!The “airzooka” is loaded with carbon dioxide gas, using either dry ice (be extremely careful) or a fog machine.
HOW TO CRAFT A FUN PAPER BAG HAT
What can you do with a paper grocery bag? Crumple it up a bit and form a Mad Hatter hat! Use your imagination and maybe a bit of glue!
This crafty idea is provided by the San Diego County Fair. This summer’s fair will have an Alice in Wonderland theme! I can’t wait!
How to make a Mad Hatter hat with crumpled paper bags and lots of fun stuff tied and glued on!You can apply ribbons, glitter, feathers, playing cards, whatever you like to fashion your crazy Mad Hatter hat! Okay, I don’t suppose this really is science, but who cares!
HOW TO MAKE A TINY PARACHUTE
I remember creating one of these when I was a kid. I made my parachute for a toy action figure! Just look at the picture and go to work! Pretty simple!
This parachute was put together by to the Reuben H. Fleet Science Center. The Fleet, located in Balboa Park, is a super cool place with loads and loads of fun hands-on science exhibits for kids, plus an awesome IMAX theater and planetarium!
How to make a simple small parachute with a Dixie cup or object providing weight, string (or similar material) and coffee filter.
HOW TO MAKE A SUPER COOL STAR WARS COSTUME!
Okay. No instructions here. Just imagination. That cool costume is actually made of all sorts of Star Wars toys! Incredible. I’m guessing that wicked-looking dude is on the Dark Side.
I believe this guy was part of the STAR WARS Steampunk Recycled Fashion and Engineering Challenge.
Yeah, making a cool costume out of Star Wars toys might take a bit of glue. But all you really need is determination and imagination! (And maybe a credit card.)
HOW TO USE YOUR IMAGINATION TO BUILD ANYTHING!
What are we building here? Absolutely anything! It just takes some imagination!
Just look at some of the common household items one can use to invent cool things. I’ll bet you have some of this stuff in your own home.
I took this pic at a fun table display in the Qualcomm Thinkabit Lab tent.
What can a person make with this stuff? Anything!Objects you can use creatively include popsicle sticks, plastic spoons, straws, tubes, tape and buttons.
HOW TO MIX UP SOME SNAIL GOOP
Slime…snail goop…boogers…it’s all the same good stuff. At least it’s the same mixture of borax powder, water and white glue. A truly yucky and wonderful substance. Science rocks!
Thanks (maybe) to the Steam Maker Workshop for this gloppy sight.
Okay, snail goop is pretty much the same stuff as slime. But I like the name!If a snail made that much goop, it would be a monster. Fortunately, that monstrous snail would be slow.Kids and curious adults were learning all sorts of cool concepts at the 2016 San Diego Festival of Science and Engineering at Petco Park.
HOW TO CREATE A 3-D OPTICAL ILLUSION WITH STRING
Here’s a cool experiment that demonstrates concepts in math and spatial geometry. Perhaps imagine that the string is a ray of light. From the “tower”, stretch the string so that it touches each of the four top corners of your cube, and plot where the string finally reaches your piece of paper. Connect those points with lines the way my photographs show, then look at the image from the end of the string! It looks like some sort of weird optical illusion, but you’ll see the result actually makes sense!
This exhibit was provided by San Diego State University’s InforMath Collaborative.
By using a string attached to this tower, you can plot the projected corners of a cube or other three dimensional object onto a flat two dimensional surface.After drawing the cube’s base and drawing lines to connect the square with the projected corners, I ended up with this cool figure.When I peered at the image through a hole near the end of the string, I saw a perfect cube! Cool!
HOW TO ASSEMBLE A COOL TENSEGRITY CONSTRUCT
Oh, man! I think you could construct most of this cool stuff with Tinkertoys. Look at the diagrams and go wild! You’ll need lots of rubber bands!
Tensegrity is another science concept that was being demonstrated at the STEM education event. A friendly gentleman explained that the sticks are like bones and the rubber bands are like muscles. So human beings and other critters are examples of tensegrity!
Oops. I apologize for not knowing who put on this exhibit.
What the heck is tensegrity? A funny word created by Buckminster Fuller. You can use rubber bands to add tension to popsicle sticks and create cool stuff.Check it out! Tensegrity is also sometimes called tensional integrity or floating compression.These guys formed a huge tensegrity thingamajig using pipes and big rubber bands. I suppose one could use bungee cords, too.Look at all the tensegrity objects you can make!
HOW TO MAKE A VORTEX CANNON
Here’s a pic that has exact instructions on how to build a vortex air cannon. Looks really easy! (As usual, click the image to enlarge it.)
Uh, oh. I don’t know who created this exhibit, either. I forgot to take a picture with their name. My research got a bit sloppy. Sorry about that. Whoever had this table–very cool!
The vortex cannon shoots air in–you guessed it–a vortex.To make a vortex cannon, insert a cut narrow water bottle into a larger plastic Solo cup, just like the photo.Then cut off the nozzle of a balloon, and stretch the balloon over the open end of the cup.
HOW TO STIR UP LAVA IN A CUP
Finally, I’ve heard of java in a cup. But lava in a cup? Why not?
Adding salt to the floating oil makes the blob sink. It has become more dense than water. When the salt dissolves, the oil rises again!
Those instructions look super simple!
To make “lava in a cup”, use food coloring, vegetable oil and salt! It’s easy!You can then use that colorful lava in the cup to make some colorful art! Awesome!
That’s it! You now have a whole bunch of cool and creative science projects to try out! Have a blast!
Hey! Are you a kid? (Or even a boring old adult?) Try starting a blog like Cool San Diego Sights! You can blog about anything in the whole wide world. It’s lots of fun! And it’s pretty easy, too!
