The Pumponator Clear PUMP0212R Water Balloon Pump was invented by 8-year-old Lexi Glenn who made it specially to be filled with ease. It comes in five spectacular translucent colors: blue pink purple green and red allowing kids to play competitively if they want to. The water balloon filler comes with 300 biodegradable balloons included so you can have an exciting battle right away. New features include a special nozzle that works with all sizes of balloons. It also has an attached tying tool that knots balloons easily. The red balloon filling pump has a slim size letting you easily store it in a garage or play room until it s time to use it.
