Bubble Hurricanes

Bubble Hurricanes

CAUTION: This experiment uses a hot plate. Please use adult supervision if attempting to recreate. Bubbles are a great resource for fun and physics. They provide interesting insight for optimization and can even be used as models for atmospheres. Scientists are able to use bubbles as models for the atmosphere because they are very thin

The Coolest Molecules

The Coolest Molecules

CAUTION: This experiment uses dry ice (-109˚F) and liquid nitrogen (-321˚F). Proper safety equipment should always be used when handling these substances. Physics tells us that pressure, volume and temperature are all linked when talking about gases. So what does this have to do with solid carbon dioxide (dry ice) and liquid nitrogen? When dry

The Case of the Mysterious Gases

The Case of the Mysterious Gases

Can you solve this mystery? There are three balloons, each filled with a different gas. One is nitrogen, one is helium and one is hydrogen. Without knowing which is which, we can conduct a couple different experiments that lets us gain information to determine which gas is in which balloon. But before performing the experiments,

Make Your Own Cloud Chamber

Make Your Own Cloud Chamber

Clouds usually form when water molecules clump together on small particles of dust in the air. These particles are called condensation nuclei. In clean air, they’re hard to come by, so clouds don’t form easily. If conditions are very humid, the air can become supersaturated, or rich with water molecules that would form a cloud
