The 33ft. two lane Slip-N-Slide is awesome for the summer heat. Our inflatable Slip-N-Slide is different in that two people race against each other to see who can get to the wave first. The inflatable wave at the end of the slide stops any quick sliders from falling on the ground. Water pours on top of the participants head to increase their speed and sliding potential. The Slip-N-Slide requires a dedicated 110V, 20amp household outlet. Fun Source is not responsible for power issues. Fun Source does rent generators should power be an issue. The Slip-N-Slide requires 1 blower.
