Jello High Dive

Fill an olympic-sized pool with jell-o and get someone to do a dive off the high dive into it, perhaps on fire, or naked, something to make it worth while because if you just wanted them to do a dive they would know something is up.

Maybe even get a huge water slide and then the jello pool would be at the end of the slide so they come down this huge water slide (in a toboggan like cool runnings and on fire) perhaps an ice toboggan ride on fire so its liek cool runnings but its hot running instead, hot runs (insert diarrhea joke here) but the end result a pool full of jell-o is pretty cool.
