Don’t try this at home

Smarter Every Day: Handheld TESLA COIL GUN at 28,000fps.

Tesla Coils are a lot of fun, but I don’t recommend doing this at home unless you know what you’re doing. Very cool to watch in this video, though.

Physics Girl: Bizarre Spinning Toys. (YouTube, 5:23)

“Spinning toys and tops have unusual behaviors. The famous tippe top flips itself over and spins on its stem. The PhiTOP stands up on its end, which you can also do with a hard-boiled egg. These behaviors all have to do with torque and angular momentum, like a bicycle wheel precessing around a rope due to gyroscopic behavior.”

Dancing water droplets in an air bubble inside a water bubble in space

Smarter Every Day 160: The WALKING WATER Mystery (in SPACE and SLOW MOTION!). (YouTube, 12min)

Destin Sandlin explains why you often see water droplets dance or bounce on the surface of water instead of coalescence occurs.

This video features astronaut Don Pettit, who did a cool experiment in space: He attached a big water bubble to a speaker, then inserted an air bubble into it. When he played cello music (by Yo-Yo Ma) through the speaker, little water droplets would detach from the water and bounce around inside the air bubble. You can see it in the above video starting right here.
