Product Description
Water Wheel Timer: Toys & Games. Since the water is denser than the oil, it is forced through a funnel and down on to the paddles of the little wheel. This cute and colorful timer has two wheels that spin as droplets of neon colored water spill through a funnel and catch on the wheel in the lower chamber. Simultaneously, lighter drops of oil rise through the colorful water and spin a wheel in the upper chamber. A fun lesson in the density of liquids, this timer goes for about two minutes until you turn it over to start it again.
