Fun Source has replaced our old water bombs with the new 4 person inflatable Water Bombs. This unit is complete with a top to keep stray water balloons contained… The unit has a water balloon filling station. Awesome, awesome fun for youth groups and kids wanting water balloon action… and different then most water attraction rentals. You will love the New Water Bombs!!! You will need a water outlet within 100 feet of the Water Bombs. The Water Bombs requires a regular household outlet for power… FUN SOURCE IS NOT RESPONSIBLE FOR POWER NEEDS. We do rent generators should you need power for your event. One generator will power 2 inflatable blowers.
