The WeaponOfChoice for the BrattyHalfPint and {{Youngsters}}. Water Balloons may be used alongside [[BratsWithSlingshots slingshots]].

The contents will not always be water-- it could be jelly, ink, or something more... [[UrineTrouble foul]]. Either that or some jerk will bring out the hose.

Expect college science geeks and/or medical students with too much time on their hands to build a water balloon slingshot out of lab materials, or some other ridiculous contraption.

Wet T-shirts and swim suits may lead to SexySoakedShirt.
