VIDEO:

I *always* enjoy it when students pass along very cool physics videos and a student shared THIS astounding video a couple of years back. Let's take a gander now. I'd recommend taking a few notes as you watch

Oh and speaking of which, our own Isabel in 4th period shared another remarkable video with me today, and we'll be viewing that tomorrow
