We launched ourselves behind a jet ski on thrift store items off a ramp and here is the video of what happened. Some of the thrift store items include water skis, a wakeboard, a boogie board, an inflatable air mattress, an aluminum foil tray, a Lightening McQueen Kid's monster truck, and a caterpillar rocking horse.
We attached a rope from the jet ski and held onto it and ramped and did tricks with these items
