Flying in a Hot Air Balloon (With a Glass Bottom!)

Flying in a hot air balloon can be a very pleasing, tranquil experience. You float high above the ground, with a nice cool breeze in your face and the burner offering the only sounds. It is a very relaxing feeling. That is, unless you happen to be aboard the world's only glass bottomed hot air balloon like the one in the video below. Then you might be just a tad bit unnerved!

Actually, this looks really cool.
