Well, in my research in last 5 years there has been 5 deaths on bounce houses and all by adults. Simply put, a bounce house was designed for children. When adults go in it, their inner superman comes out and they think they are invincible, add some beer and they are superhuman.
Here are some facts:
For anyone to play on an amusement ride, they should not be effected by drugs and alcohol. So how many adult parties are out there that this would not be the case.
Adults leave them alone. Parents always think that they can play with their kids inside the bounce house or support them while they are in there or help them play on the objects inside but more common than not the adult loses balance or falls over, landing on other children.
