A pair of bicycles are hooked up to power a device which transfers water from one container to another. The device delivers a squirt of water to the person who transfers the least water; the winner gets a “shirt” (a shirt sign pops up in front of them). The fun is not only in participating, but also in spectating- the eccentrically dressed presenters will often “fix” the result (for example, allowing a child to beat their parent). Ideal as a side show for cycling events, or at any summer family fun day.
