Upon tossing a coin into the bowl, it rises up on a column of water accompanied by a crescendo of native drums and wildlife. The coin transforms into a fizz of bubbles and vanishes. The bowl returns to the surface awaiting the next coin and the jungle quiets again.

We built a square container from stainless steel to contain the device. This we stuck in a hole in the pool floor. It emerges into the workshop below where all the control systems are located, along with the coin collection reservoir. It runs 24hrs/day, 7 days/week.
