Really neat relativity example. I'm not trying to start any contests of one-up-manship or anything, and I'm not completely familiar with the Physics Force, but you did remind me of the Physics field trips we took when I was in H.S. in Albuquerque, NM. Standing on the catwalk over one of the 30,000 gallon water-filled first-stage capacitors of PBFA II (Particle Beam Fusion Accelerator II) was pretty cool. It's now the Z-machine (if anyone reads SciAm -- it was in there a few months ago.) But then again, the fathers and mothers of more than half the class worked out at Sandia National Labs or consulted up at LANL. (BTW, isn't the merry-go-round an example of the Coriolis effect, not relativity? I'm just a math guy, I could be wrong.)
