The Jackass cast are placed in a large plexiglass container. Nudity is optional. They are then filled-up in baking soda to their chest. Then a Big Dump Truck or Tanker truck or at least a whole bunch of dudes with open drum barrels filled with white vinegar are dumped into the baking soda filled big-box. A huge volatile mixture fizz takes place. In the end. it will look like a gigantic ejaculation has taken place!!
