I just heard on Paul Harvey in the radio (570).  He gave a story about a man that had gathered rubber bands and made a huge rubber ball.  He wanted to know how high it could bounce.  So he took it in an airplane a mile or so above the Mojave Desert and dropped it.

It hit with a thud, didn't bounce at all, it only left a hole in the desert. Did he have BLM permission?  Did he even ask?  Maybe we should go there to try the bowling ball experiment??
