More ideas - I want to try some high speed photography; water balloons popping, hitting the ground, being shot by a pellet gun. Slapping someones chest. Water drops, w/ or w/o dye. Fruit dropped into water tank, blown out background. Fruit dropped into milk, (strawberry). Dropped into spoon w/ milk. Strobe shot of golf swing, baseball swing.
