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.
Cory Howard has never felt cooler in all his life, and now you can join in the fun too! Get ready to (safely) snap some rulers using the power of science!

What is going on? The random movement of the wobblebot is caused by the spinning shaft of the motor extending down through the center of your CD. By adding a glob of glue from your hot glue gun, you are not only protecting the floor from scratches, you are also increasing the friction between the floor and the motor shaft. Once the wobblebot is turned on and the shaft begins to spin, the force between the two surfaces will cause the wobblebot to move in one direction.
