This electric water bead shooter is super fun to play with and have water gun fights. The water beads need to be soaked in water for a few hours, but once they reach full size they can be loaded into the gun and away you go. The scope sight holds roughly 100 rounds, with the power of the gun that can last anywhere from a few minutes to hours on end if you conserve your amount.
The only con is how loud the gun is when it shoots and rapid fires. Also the water beads burst into gel pieces so it is harder to clean up, or you can leave them and they will degrade over time
