There is chlorine water in the zorb, this is the only sanitized action taken. The water is dumped and refilled after each rider.
No not sanitized. Water from previous rider is emptied, refilled after each rider.
They are filled with chlorinated water. They dump out the water and fill it with new water for each new ride.
I don't know when you get out from coming down the hill they do not. They put the 2 balls back on track and send them back up hill, but I could not see if they did or not.
