In simple terms, the frozen glass bottle, dime, and hot water on it all try to achieve the ambient temperature of the room (i.e. the whole and neutral state). This causes a physical reaction of the dime dancing as the cooler air from the frozen bottle clashes with the warmer air from the water. Metal works well in this experiment because it heats and cools quickly. Continue reading
