Waterbed Mattress Jump
When I was younger my parents bought a new waterbed mattress and gave the old one to my sister and I to use for fun. I filled the mattress up with air until it was an oddly-shaped ball. My friend or I would sit on the mattress while the other would run at full speed and jump onto the mattress, sending the sitting person flying several feet through the air. It was so much fun that I wish I still had that mattress!
So... if you just happen to have an old, unused waterbed mattress, give it to your kids. They will love it! Just make sure the jumping child doesn't land on the person sitting.
