Both adults and kids can benefit from these! Makes it soooo much easier to fill up hundreds of balloons without spending the day before the big water balloon event! Although kids these days will never appreciate the hard work that we had to put in for the big battle.
If you and your kids enjoy playing with water balloons but don't enjoy filling each one by one then I highly recommend Bunch O Balloons. They quick to fill up. You can fill several balloons at the same time. They are fun and easy. A great summer activity during a hot day.
Costco has a massive pack of these! We love these water balloons!
