'Spit Balls' are spit ball toys from Edmund Scientific. These spit ball toys grow to 200x their original size and are perfect for pranking unsuspecting individuals. Thanks to slimy, non-toxic, scientific polymers Spit Balls are able to recreate the texture and velocity of human saliva and will explode on target.

These spit ball toys retail for $5 and are perfect for fun-loving kids who may have difficulty producing saliva (or who are just saving their spit for other useful things like aiding in food digestion).
