how can i make an inexpensive dunk tank ?

Question

inexpensive, easy and looks good

Answer 1

Make it manual.

- Have the target be a bell or something that make a noise when hit.
- Have a board across the top of the tank where the 'dunkee' sits.
- Have someone stand behind the tank, the 'dunker'.

When the bell rings, the 'dunker' pulls the board out from under the 'dunkee'.

Answer 2

ok get a large barrel of some sort and a seat then hook it up to a pully system so when people hit the cardboard target the chair falls and people go into the barrel
