CAUTION! Do not try this at home. This experiment uses liquid nitrogen which is EXTREMELY cold. Safety precautions were taken in the filming of this video. Many know that liquid nitrogen is extremely cold, at -321ºF. When it is exposed to extreme temperature differences, you can observe something called the Leidenfrost Effect. To learn more
If you’ve ever brought a match to a balloon (or been in our Atmosphere and Gases class), you know that fire and balloons don’t mix, but what if you could prevent a balloon from popping when it comes in contact with fire? The answer to this dilemma can be found in the simplest place: water.
You can make a hovercraft from the comfort of your home! For this DIY science, all you need are a few things that you probably already have around your house: a CD (preferably one that you never want to listen to again), a bottle cap (preferably resealable, otherwise just poke a hole through the center),
You can use slinkies to demonstrate all things waves! Start with the basics: wavelength, amplitude and frequency. Once you’ve got those down, then you can play around with some things that are a bit more complicated like wave type, standing waves, and superposition. Longitudinal waves, like sound waves, expand and compress as they travel
You can do this experiment at home with just a few things. 9 Volt battery, steel wool, non-flammable surface, and some adult supervision. After fluffing up the steel wool a bit place it on your non-flammable surface, then simply touch the 9 volt battery to it. It’s that simple! But what’s really happening? When you
