Nothing better than arming children with little balloons full of water and letting them have at it. This Waterbomb Combat Kit, $7.95, comes with "weapons-grade water balloons" color-coded so you know who won the final battle, and water balloon pumps (cuz who hasn't been hit by friendly fire while filling a structurally unsound balloon on the spigot?) Make war, not...um, never mind. Hey--ages 5 and up, please. From our beloved Geekdads.
