Once upon a time, trampolining was like a date with danger in the backyard – one false move and oops, fat lip! Things are a lot less dicey at Sky Zone, two enormous warehouse in Sydney and Brisbane where you can jump alongside mates inside the Stratosphere, get physical in the dodgeball zones, bounce your way through a basketball game in the Sky Slam or, once you're dizzy from all that jumping, dive into a pit filled with gigantic foam squares. (Good luck getting out!)
