In this video I explore some crazy ways to cook an egg, and kind of go into the science behind it. Plus, its a great excuse to break out the flamethrower! Making a squirt gun flamethrower is very dangerous.

I get a lot of...

This video explains the concept and composition of transformers, which are devices that can increase or decrease the voltage of an alternating current. It uses the example of transformers found on telephone poles to illustrate how they...

In this week’s episode, we examine electric eels, test out a new at-home screening test for people on blood thinners, learn about a new app for reporting floods and, finally, examine how RoboBees use static electricity to stick to surfaces.
