Liquid oxygen has unusual magnetic properties. This demonstration with the MIT Technical Services Group and a crazy blowtorch demonstration on the curie point of iron share a glimpse into how different kinds of magnetism work.

Can you answer the spool riddle? Special guest Anne Wojcicki joins Physics Girl for the answer(s?!) to the hiker riddle and to hear the next riddle

How does soap change the surface tension of water? I have used my degree to make a fifth video -- for you all -- to explain this very question.

Learn how to make a wispy cloud come out of your mouth, even when it's not cold out. Like any awesome trick, physics is to thank for the mouth cloud. This simple and fun demonstration can be used to explain the cloud in a bottle experiment, and real clouds in the sky.

What happens when you drop a perfectly balanced stack of balls? And how is the result like a supernova? The classic momentum transfer demonstration, taken to the next level. A big thank you to my nephews and niece Drew, Max and Whitney for creating the trampoline footage! Thank you to the Vlogbrothers for sponsoring this video, to Kyle Kitzmiller for filming, and to Island School on Kauai for providing the balls
