In a new clip from her upcoming 'Katy Perry: Part of Me' documentary, the 'Teenage Dream' singer shows fans what she does on her days off between concerts, which typically involves lots of thrill rides and visits to water parks with her sister.

Katy's big sis, Angela Hudson, says in the video, "We always had this deal that when she made it big, that I was gonna work with her and we were gonna be together... My sister, not only does she work hard on tour, she likes to play hard on tour."

Cut to shots of Perry on a raft, about to head down a water slide. After a few clips from the water park, viewers see the sisters get strapped into a bungee apparatus. Katy enjoys the ride, but her sister, who's afraid of heights, comes away from the experience with a queasy feeling.

'Part of Me' hits theaters on July 5. Aside from feeling a "connection to fairytales," Perry told MTV about the movie: "It's the most intimate I've ever been. I mean that in a non-sexual way ... I mean it in a vulnerable way. And so I'm not scared of it because I think it's important for me, and important these days, for people to not think people in my position are perfect and that if they want to achieve this type of dream or achieve a goal that they have to be flawless. They don't."
