Conceptually similar to the Snowman Kit we featured earlier today, but way yuckier in execution, these tiny polymer Spit Balls react with water to grow 20 times their original size. Throw ‘em and they splatter; handle ‘em and you get slimy. If by “disgusting” you mean “awesome,” then I wholeheartedly agree.
$4.95 per pack from Scientifics Online.
