The Physics of Bubbles

Courtesy Henry M. and Nina D. - they both thought this is WAY COOL!:

I think it is really interesting how something that seems so simple as a bubble popping is actually more complicated than you may think. It was also really awesome at 2:38 when he shows how you can put your hand inside a bubble. While this video doesn't exactly discuss any concepts we are studying right now, it reminds me of how we take a seemingly simple process in class, and find that there are many different concepts of physics in play.
