> The Bailey Ball was an Alpine Center attraction developed and tested, but never opened to the public, as a result of those tests. It consisted of a large foam sphere in which a rider could be secured, and then rolled downward. The plan was to do it on a track with PVC pipe as its outer rails, and one was built alongside a ski trail.[11]: 16:25
> The designers neglected to take into account the tendency of PVC pipe to expand in heat. During the first test, with a state inspector present on a hot summer day, the ball, with a man inside testing it, went off the track as a result of the pipe expanding and bounded down the adjacent ski slope. It continued through the parking lot, across Route 94, and came to rest in a swamp. After it came to a natural stop at the bottom, the inspector left without saying anything and park management abandoned the project.[11]: 16:25 [43]
