Broken Projectiles

Hacky sacks make pretty good projectiles when they slam into something soft like the grass or a hand... but... or the asphalt, or a park bench and they don't last long.  I made my own out of leather and the innards of a broken one which lasted wonderfully until it landed in the lake.  It's funny how things filled with rocks don't float very well.   The woven hacky sacks work well though a little more expensive.
