How do they stop the water splashing to the end of the room when they take off and land? It takes a long time to fill and empty a pool.
I'm sure if they can come up with the engineering required to make something that size fly, filling a pool won't be too hard oh, and the original link doesn't seem to be working.
bob, all you need for that is a ping pong ball on a bit of string. the solution to the pool problem is to put a lid on it. it might slosh about a bit but it won;t leak.
