The wonder of polymers makes these slimy spit balls possible. Easy to make and fun to use, spit balls grow to 200x their original size and are slimy to the touch. Slip, slide, and bounce the balls until they explode on target.
"Growing to 200x it's original size"...."slimy to the touch"...."bouncing the balls until they explode on target"....remind you of something else? Yeah, me neither.
Finally Some Real Innovation! Polymer Spit Balls Grow To 200x Their Original Size [ohgizmo]
