The Bubble Drum looks like a lab gone wild. It consists of suspended pipes that hold coloured water, and produces rhythmical sound and movement by releasing bubbles of compressed air. The physical force of these bubbles makes the pipes jump.
On its own, The Bubble Drum plays bubbly beats. But there is also a control station. The visitor who choses to be in charge of the control station, turns into a mad scientist-musician. By becoming a performer, the visitor completes the piece.
