We know they're fun, but are they really safe?
Recent incidents caught on tape show that bouncy houses and moon walks might need more regulation.
Bouncy houses can fly through the air when high winds picked them off the ground.
When that happens, anything or anyone inside is put at risk.
"I think we all need to stress to our customers the importance of anchoring them and the importance of deflating them in high winds. If they think its unsafe, it probably is," said Clyde Dickens, owner of A1 Party Rentals in Lufkin.
Dickens says reading the directions can save party hosts a lot of trouble.
