Wicked Science

Posted on by

Bright, swirling smoke in shades of neon pink and electric green forms bold, energetic shapes, creating a striking abstract background with vibrant colors.

Calling all citizens of Oz and abroad! You are cordially invited to enroll in Shiz University’s elite sorcery class to learn the science behind the magic. That’s right…we’re off to see the science!

The Cotsen Children’s Library, Department of Chemistry, and Science Outreach at Princeton University were delighted to present a morning of hands-on activity tables, followed by a 45-minute auditorium show with plenty of glitter and gravitas!

As Ozian’s entered the event floor, they were greeted with tables staffed by graduate and undergraduate students from Science Outreach at Princeton University (who gamely showed up dressed in pink and green!).

Kids wielded static electricity wands, learned about magnetic levitation, unveiled the Grimmerie’s invisible ink, tested Glinda’s bubble travel potion, and examined the pH levels of popular potions.

There was also a yellow brick road magnet game table, and, just in case you missed it in the slideshow above, a truly magnificent dry ice tabletop tornado, which Katie constructed with the help of this Steve Spangler video.

After the activity tables had been thoroughly perused, Angie Miller from the Department of Chemistry invited students to attend Shiz University’s very own “Potions 101” class, which was held in the Taylor Auditorium on Princeton University campus.

Angie the Amazing lead the class through the tenets of the scientific method with emerald flames, rainbow beakers, conservation of mass, water boiling at room temperature, and more! She also defied gravity with the Meissner Effect (i.e. cooling a superconductor with liquid nitrogen to levitate a magnet). My personal favorite? Candy combustion – a dramatic demonstration of what happens when potassium chlorate meets Skittles:

Of course, it wouldn’t be magic/science without things culminating in fire and explosions, so Angie ramped things up with metal salt flames and firework balloons. Katie and I both managed to get footage of the fun:

The event was absolutely wonderful, and we would like to thank Angie Miller in the Department of Chemistry, Paryn Wallace with the Science Outreach at Princeton University, and all the graduate and undergraduate students who volunteered their time to reach out to community families! We appreciate you so much!

Sneak Peek: Wicked Science

Posted on by

We’re off to see the Wizard on a yellow brick road that also…wait for it…defies gravity, thanks to the magic of science and magnets!

This weekend, we’re hosting Wicked Science, a thrillifying event in collaboration with Science Outreach at Princeton University and the Department of Chemistry. In addition to a 45 minutes auditorium show, the event features hands-on tables staffed by Princeton University undergraduate and graduate students. The cool golden magnet tiles you see above are part of a game called Kollide (ages 8+, retails for $15).

To play the game, you arrange a rope in a circle and divide the 20 magnets evenly amongst the players (you can have up to four players at a time). Then each player takes a turn placing a magnet in the circle. As you can guess, the more magnets in the circle, the more they get attracted to one another and start scooting, twisting, and snapping together. If that happens, you pick up the bundle of snapped magnets and your turn is over. The first player to get rid of all their magnets without any magnets clumping together wins!

It’s super fun, especially when the magnets start to threateningly wiggle and move as you try to place them, then suddenly snap together. It’s like magic!

Swiftie Science!

ARE YOU READY FOR IT? As you might recall from our recent sneak peek, we joined forces with our friends at Science Outreach at Princeton University and the Department of Chemistry to host a fantastic celebration of science and the lyrics, visuals, and overall awesomeness of Taylor Swift! The crowds were enchanted, bejeweled, and the alchemy exceeded our wildest dreams! How did we mastermind this event? Dear reader, it was a wonderland!

The event was divided into two parts: 1) hands-on activity tables; and 2) an auditorium show. Part one featured five hands-on demonstration tables that uniquely represented a Swift song. This part of the event was led by the amazing Paryn Wallace, Associate Director of Science Outreach, and a talented team of Princeton University undergraduate and graduate student volunteers from Science Outreach at Princeton University.

At the “Shake it Off” table, kids could learn about non-Newtonian fluids by examining the curious properties of oobleck as it danced on top of speakers blasting Swift’s music. Nearby was the “Clean” table, where budding scientists could determine the pH levels of various water samples (tap, bottled, rain, etc.) using litmus paper. At the “Blank Space” table, kids learned about chemical reactions as they revealed lemon juice invisible ink messages with a heat source.

One of my favorite tables, however, was “All Too Well.” This classic song is all about memories, so the table featured Nitinol wire. Because of its unique atomic structure, Nitinol wire can “remember” its original shape during temperature changes. It’s pretty astounding to watch. The final hands-on table was “Mastermind,” where we literally brought Taylor’s song lyrics to life as chain reactions of “dominos cascaded in a line.”

Once the tables were thoroughly explored, it was time for part two, the auditorium show (which was, ironically, held in the Taylor auditorium inside the Frick Chemistry Building)! The show was led by the extraordinary Angie Miller, Lecture Demonstrator in Princeton University’s Department of Chemistry.

Angie had the task of pairing Swiftie concepts with principals of science, so in preparation for the show, Katie and I steered Angie to what we believe to be Taylor’s most science-y music video, “ME!” Here, Taylor cavorts with cats, clouds, rainbow prisms, and colorful foam.

So Angie talked extensively about the scientific method while bursting hydrogen balloons, making nitrogen clouds, and testing audience predictions of marshmallow cat behaviors in vacuum chambers. Angie invited the young scientists to gaze at line spectra of various gases, created colored fireballs with metal salts and a Bunsen burner, and…in a grand finale…played the “ME!” video for the crowd on the big screen while coordinating larger versions of the previous demos, capping everything off with a six beaker rainbow deluxe version of elephant toothpaste!

Peppered throughout the show were audience trivia questions for friendship bracelet prizes. Before the marshmallow cat demo, for example, I asked the audience if someone could name Taylor’s three cats. They sure could! First names AND last names (though I was secretly waiting to hear someone shout “Dibbles!”).

The auditorium show’s crescendo was the “ME!” video, but we had one more fantastic surprise in store for the crowds that day…a cameo appearance by Taylor!

Well, that’s not ACTUALLY Taylor Swift. It’s Princeton University sophomore Margo Mattes! A Politics major and massive Swiftie, Margo gamely volunteered to play Tay and take photos with the kids. She was so utterly fantastic, we can’t thank her enough for giving her time and exuberance to this event!

As the happy crowd exited the building, we handed out friendship bracelet kits made out of UV beads. These plain beads react with sunlight and change to rainbow colors. Just a little extra TS science to take home!

I can’t even begin to express my gratitude and appreciation to everyone who made this event possible. Thank you to the students from Science Outreach at Princeton for your ideas, boundless energy, and time. Margo Mattes, thank you for bringing your sweet brilliance and enthusiasm as Miss Americana. And a massive shout out to event masterminds Paryn Wallace and Angie Miller. You were so game to try this, and Katie and I absolutely loved working with you!
