Can’t . . . Avoid . . . Collision
Remember the conservation-of-momentum problem you did in 1st semester physics, where the projectile breaks into two pieces at the apex of its flight? Now multiply by Avogadro’s number (and then an additional order of magnitude or more)
Momentum’s conserved, even in slo-mo.

I love water balloon videos - so much physics in a five cent package. Slow motion water balloon bounces are particularly interesting because the elastic boundary allows both surface and body modes of oscillation. Here’s a typical example from Youtube: http://www.youtube.com/watch?v=oxbFrGFNVO0
Thanks again for the light-in-a-bar comment, that’s easily the most interesting physics question I’ve seen all summer.
