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 . . .  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 creations and creators who like building cool stuff!

Holographic painting–a revolutionary art movement!

Unique holographic artwork painted on glass as seen through a Gaslamp window. Reflections of life on the street are also visible.
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!

Today I moseyed around Del Mar and Solana Beach. My walk included a couple of stimulating hours at the San Diego County Fair. I just wandered about, soaking it all in, and found my feet heading toward my favorite part of the fair, the Design in Wood Exhibition.

Some of the best wood artists in Southern California–the world, for that matter–submitted their incredible pieces this year to be judged. The exhibition, a collaboration with the San Diego Fine Woodworkers Association, is celebrating its 35th year.

Here is some of the wildly creative woodwork that really caught my eye. You’ll notice many pieces have an Alice in Wonderland theme. That’s because this year’s San Diego County Fair is all about that timeless children’s book penned by Lewis Carroll. White Rabbits, March Hares and Mad Hatters abound! Everywhere you turn there’s a tea party or a grinning Cheshire Cat!

The Alice in Wonderland theme intersects with Steampunk, of course, so many fantastic contraptions and quirky bits of wood art are included in the exhibition. Take a look!

Artist creates amazing lumen and cyanotype photos!

Uniquely beautiful Fern Lumen by artist Patricia Grabski.
Uniquely beautiful Fern Lumen by artist Patricia Grabski.

This weekend you have an opportunity to see something really unique. Patricia Grabski is displaying her amazing lumen and cyanotype photo art in Balboa Park. Her work is part of a five artist exhibition called Ain’t Nothing Like a Dame, which you can enjoy inside Gallery 21, in the always wonderful Spanish Village Art Center.

I learned that cyanotype printing was invented in England in 1842. Utilizing two chemicals, ammonium iron citrate and potassium ferricyanide, this process was used to create early blueprints. In 1843, the world’s first woman photographer, Anna Atkins, placed organic materials onto paper coated with cyanotype; when exposed to sunlight, ghostly, artistic photograms were created.

Lumens is a very similar process that uses old unexposed black and white photo paper. Exposure to sunlight creates all sorts of fantastic colors and effects.

My own poor photographs don’t do this fascinating artwork justice. You have to see the subtle detail in person. So head on over to Spanish Village tomorrow.  Patricia Grabski’s work will be displayed through March 14. If you want to contact the artist, her info is visible in one photo.

Patricia Grabski is currently exhibiting her unique creations in Gallery 21, in Balboa Park's wonderful Spanish Village Art Center. Her pieces are available for purchase.

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 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 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 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 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.)

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.

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!

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.

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.

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.

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!

Electric wicker carts returning to Balboa Park!

The electric wicker cart Electriquettes are returning to Balboa Park early 2016!

The wicker carts are returning to Balboa Park! What fun!

The now famous electric motorized wicker carts were introduced to Balboa Park one hundred years ago for the 1915 Panama-California Exposition. They were called Electriquettes. They were an enormous success!

Starting in early 2016–perhaps February I was told–visitors to Balboa Park will be able to rent the new wicker carts at the San Diego Air and Space Museum. The test program will run for a year, and I hope it’s successful!

I learned that the carts travel at about 2-3 miles per hour, an easy-going speed appropriate for a pedestrian and family-friendly city park. As I understand it, the carts will be restricted to Balboa Park’s core area. They appear super easy to operate–one just steers and applies power! Perhaps the coolest thing is that these vehicles are a reasonably close representation of the original Electriquettes.

Check out the San Diego Electriquettes website, and you can see additional historical photos!

I can’t wait to ride one!

UPDATE!

The Electriquettes began running toward the end of March! I even saw a couple driving about the Plaza de Panama, but didn’t have my camera handy! I’ve learned they can be rented right in front of the Reuben H. Fleet Science Center!

A modern Electriquette is displayed in Balboa Park, in anticipation of its reintroduction. The unique wicker carts will be rented by visitors at the Air and Space Museum.

History of Electricity on a cool OB mural!

Benjamin Franklin with his famous kite, and Thomas Edison, inventor of the light bulb and phonograph, are depicted on very unique mural in Ocean Beach.

Here’s a cool (and somewhat unusual) mural that I spotted on a wall next to a parking lot in Ocean Beach. It’s called History of Electricity! Benjamin Franklin, Thomas Edison, Guglielmo Marconi and Alessandro Volta share the OB streets with images of pop culture icons and surfers!

This artwork was created by Janis Ambrosiani of Walls With A View. Take a look!

Robot Resurrection is being assembled for the Maker Faire in Balboa Park this weekend!
Robot Resurrection is being assembled for Maker Faire, which takes place in Balboa Park this weekend!

A super gigantic fire-breathing robot is coming! You don’t believe me? I saw it today!

The amazing 28 foot tall mechanical man will be drawing a crowd in Balboa Park during the big Maker Faire event this weekend, but right now it’s lying in the Plaza de Panama being assembled!

Robot Resurrection, the name of the giant robot, is actually an articulating sculpture made from 95% airplane parts, piloted by a human operator in the metal torso. The cool creation is the brainchild of Shane Evans, who is based in Denver, Colorado. Robot Resurrection has thrilled kids and adults alike at Maker festivals all around the country!

Maker Faire kicks off Saturday at 10 am. At this epic celebration of technological and artistic innovation, all sorts of inventions and gizmos will be outside on display, including cupcake cars, a giant 12 foot electric giraffe, drones, and something called a Battlepond! Ten of Balboa Park’s museums will also participate, with related exhibits and cool events of their own! If you like this sort of stuff, you’d better go check it out! I’ll definitely be there!

Maker Faire San Diego will include many cool sights up and down El Prado, including the Imagining Zone!
