Oh, another fun one. Every once in a rare while, my mom would pull out the old parachute at gymnastics warmup (she used to trade lessons as a coach for class for us). Super fun, if you can get ahold of one. 20+ years later I only remember some of the things we'd do (run holding the edge, lift half and lower half, pop it up and run under to a new spot before it falls back down like musical chairs, etc., but I can ask her if you find one. Never occurred to us we were running around, stretching etc. :)
