Scenes From Da-da's Mind-Roasting Summer

Kids, THIS is a demonstration of centripetal AND centrifugal force.
Either way, your blood should be pooling somewhere -- and NO, we aren't there, yet.

Ping Pong Ball vs. Giant Testicle

This is very interesting -- provided you like fluid dynamics and... well, pain -- and if you've studied any physics or chemistry or casino operations, you know that it's all about fluid dynamics and pain (and not just giant testicle simulacra). Everything acts as a fluid. Except Da-da's head. That's a solid.

Here, a water-filled ping pong ball impacts a giant testicle water-filled balloon at 600 fps (impelled by a leaf-blower, which influences the "bounce"). The obverse view is especially interesting. BTW, guys, next time put some dots on the ping pong ball, so we can see if it's spinning. And wear your cup.
