Are you hip to this? The newest fitness/recreation craze sweeping the globe (we've been told) is jumping like a madman around a room filled with trampolines and occasionally taking a dip into pits filled with foam. Release your inner six year old and literally bounce off the walls, ceilings and navigate some interesting obstacles. The perfect way to spend a rainy day, blow off some steam or just have some good old fashioned fun. Entrance is every hour and you must turn up 15 minutes before to get ready and have your anti-skid socks, available for purchase on the spot for 5zł.
