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!

It’s Telescope Time!

This week, our intern Melanie Zhang takes us to the stars with a simple telescope project with custom slides! You may remember Melanie’s superb honey cakes kitchen test this summer, followed by blueberry jam for Sal, and her guest appearance in our unique story time garden. Now it’s time to explore the galaxies…take it away Melanie!

I have for you a craft that is out of this world in more ways than one! I was inspired by Star Stuff: Carl Sagan and the Mysteries of the Cosmos written by Stephanie Roth Sisson (Roaring Brook Press, 2014). Star Stuff tells the story of Carl Sagan, astronomer and planetary scientist. He also once was just a young boy, looking up at the night sky, wondering about the stars. If you currently don’t have a starry night sky to look at, here’s how to make your own!

You’ll need:

  • Paper towel tube
  • Tin foil
  • Petri dish (or a clear plastic cup or plastic packaging)
  • Scissors, glue, and tape for construction
  • Stickers, construction paper, Sharpie markers, and masking tape for decorating
  • Small tissue box (optional)

First, take your paper towel tube and wrap it in a piece of tin-foil. Tape in place and fold the excess foil around the top and bottom edges of the tube. Next, decorate your telescope however you would like! I chose to wrap extra strips of folded tin-foil as well as construction paper around the top and bottom, then add stickers and label my telescope the “SKYSPOTTER 9000” with a sharpie. Now you have your telescope!

Next up is the night sky! Grab your petri dish and open it up. Using sharpies—other markers won’t color properly on the plastic—draw your space scene on the inside of both the dish and the lid. You can draw a constellation, like the big dipper, or planets, or shooting stars.

If you don’t have a petri dish, you can use the bottom of a clear plastic cup, or just about any piece of clear, flat plastic. For example, I used a plastic takeout box from lunch and cut a circle of plastic out of the lid.

It helps to draw your space scene on top of a white sheet of paper so it’s easier to see what you’re doing. Or, you can instead draw on a piece of masking tape, then cut out your drawing and paste it onto your petri dish! Just make sure that the tape you’re using is translucent and light can still shine through.

Hold your telescope up in front of one eye, then hold the petri dish up behind it, ideally in front of a light source. Take a look at what you see! Hold the petri dish closer or further away from the telescope to zoom in and out, or move it around to see all the different parts of your space scene.

Optionally, you can make your telescope a place to rest out of a tissue box! To make a telescope stand, cut a wide slot into your tissue box, wide enough for your telescope to fit in. You’ll want to cut the slot so that it extends further down on one side of the box than the other wise, so that when you set your telescope down, it is still aimed up at the sky. Keep your petri dishes inside of the box to keep them safe!

I also added a foam sticker to the underside of my telescope, near the bottom end, so that when I put it on its stand, it will stay in place. You could also tape on an extra piece of foil or a roll of paper.

And we’re done! Do you think “STARSPOTTER” or “SKYSPOTTER” has a better ring to it?

Swiftie Science!

Posted on by

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!
