Sound terrifying? Crazy? Absolutely weird?
Try all three.
I'm a little, all right, a lot terrified of things like this. I used to pretend roller coasters made me sick so I wouldn't have to ride them, I wouldn't go on the crazy steep slide at Raging Waters until peer pressure got the best of me, and no one could ever get me to go down those water slides at Magic Waters. Because of this it might surprise you that I willingly volunteered myself.
The ONLY reason I had enough courage to go on was because I thought "How many people can say they've gone down a hill in an orb?" Also I made a pact with my roommate that we'd go down together and that sealed the deal. There's no turning back from those sorts of pacts.
So they strapped me and my roommate in the orb, sealed the ball and down we went. It. Was. Hilarious. I was laughing uncontrollably, all while rolling over, again and again, and again. Might I add that we were getting some pretty good air each time we rolled over. At the end when we finally rolled to a stop (thirty seconds later) I was laughing so hard I couldn't unstrap myself. This coupled by the fact that we had landed on our escape route made for some pretty amusing strugglings witnessed by my entire ward. Oh well. It was the one of the best rushes I had experienced, so I took it in stride.
So what are you waiting for? Go buy an orb today! Then invite me to ride with you.. you'll be my best friend forever.
