Is it possible for something such as a cake or a potato to get so hot that it melts? Normally when you heat something up a whole lot, it melts, but when you put liquid cake batter in an oven it turns into a solid, then it burns, but is there a way to heat it up so much so that it turns back into a liquid? Same thing with a potato, if you heat it up, it will burn, but can you turn a potato into a liquid by heating it up too much? Plz help im rlly stuck...
