Extreme Science

Rick showed Cory the chemistry behind explosions, using clever tricks with hydrogen gas.

You can't "defy" gravity, no matter what the movies might tell you, but you can create the illusion that you can. Cory and Rick looked into the science of one illusion that's popular in science classrooms. 

Rick built a pop gun with a torch, a tube and a bottle. Cory wants to know: "why?"

In this segment, Rick showed off an antique scale his mother gifted to him, and he showed Cory how to make a scale from common household materials. 

In this segment, Rick showed Cory the science behind those paper butterflies that can fly. The two also learned how to make them. 

Rick and Cory learned about viscosity by comparing thick liquids. Britannica describes viscosity as the "resistance of a fluid (liquid or gas) to a change in shape, or movement of neighboring portions relative to one another."

Cory and Rick raced different "round things" to put inertia to the test. Rick explained how the physics of rotational inertia can result in some counterintuitive results when racing things down a track.

Rick shows Cory how to make candy glass, a safe and fake glass material used on movie sets.

This week offered a look back a fan-favorite segment of Extreme Science from more than two years ago. Corey and Rick debunked some viral videos about breakaway glass. 

Newton's three laws of motion can be summarized as:

Rick and Cory use helium and oxygen to make an explosive snack.
