Toy 3 - Fish To Go

The Fish To Go looks like any exciting wind up toy, with the exception that this game will try to teach children about energy. The small silicone fish are swimming inside a thick wall of insulation, when the toy has no energy the fish are "dead" and sink to the bottom. When the toy is wound up and released, the toy with drive in circles and the liquid will begin to heat up. As the toy is used more, the liquid will eventually simmer and the fish will swim and "cook" (change colour). The toy will be slightly warm, but not hot, to the touch. Rather than water the liquid would be a substance that heats relatively quickly. Additionally there would be a temperature indicator, with both metric and imperial measurements.
