005. Potential and Kinetic Hazards

on Oct. 26, 2008

My dad had one of these (albeit much smaller…) in his classroom. As a kid, I remember visiting the high school in the summer to help my parents clean up (or at least to be supervised sans babysitter), and I loved playing with the kinetic balls – that and looking at all the pictures in my mom's biology books. Keep in mind that grade schoolers are easily amused, and there was no internet or good cable. Anyway, you will fear and respect the power of kinetic balls! And remember that for every action, there is an equal and opposite reaction.
