We dropped it from the five stories through the middle of a stairwell. I waited on the forth floor to recover it on the rebound. It comes nearly all the way back to it's starting point and remarkably bounced pretty straight. Subsequent attempts with multiple bouncing sent it wildly around the stairs making a lot of noise. -Ron
