Go skydiving indoors
Sounds impossible, but at Airkix they have a vertical wind-tunnel, and offer an hour of indoor skydiving training which includes 2 “flights” for £40, or once you’ve got some experience you can skydive for £10 per minute. Sounds like it would be fun to try! (You generally have to weigh less than 114 Kg or you won’t get off the ground, however).
