Though somewhat violent in nature, tossing water balloons is an incredibly fun summer tradition. Though creating the ammunition can cause quite a mess in your home or yard. Let kids get right down to the fun with this Water Balloon Filler. The simple gadget that connects to your hose fills and ties a water balloon in under 30 seconds. Once kids get the hang of the easy, four-step method, they can create balloons bombs at ten times the pace it would have taken doing it the old fashioned way, which leaves more time for hurling them at one another. Lovely.
