Toaster 'Coaster

With the advent of sunbeds, along comes a wave of reports of teenage girls, younger than 16, using sunbeds just for the effect of looking like celebrities (and, no offence to them, some celebrities probably donated their brains to medical science and never told anybody - not that anyone so far has noticed the difference if they're stupid enough to get sunburnt all in the vain pursuit of looking good).

Idea:

The Toaster Coaster is a mixture of a roller coaster, a sunbed and a ghost train, in which a person, thinking that they're going to get a suntan, goes into the sunbed and, at the request of the owners ('for legal reasons' they're told), buckle themselves in. The sunbed then turns on, and the occupant realises that it's not a sunbed at all, it's actually showing the effects of skin cancer, and then the roller coaster bit starts. It takes the person for a spin, doing loop the loops and what have you, all the while the booths' speakers are parroting off the number of skin cancer deaths, and how old people look from getting exposed to the sun so often.
