There would be four platforms( determined by your height) the staff would choose a platfrom for you. Before you would go up to the platform, an instructing course would be preformed. I know it is a lot of stuff to do just to go on a ride, but saftey first.After that you would be sent up to your platform and have to put on a harness with bungee cords attached. Jumping off of the platform you would spread your arms and legs out like skydiving. But about 5 feet (or more I'm not sure) above the water, your bungee cords and harness will be relased, and as instucted you will curl up in to a ball for your cannon ball into the sea.
I don't know if it will work, but, we can always dream....
