12.New product,because if the solid melt and it will become liquid then you let it stand in 2 minutes it will become a solid and has a new shape,size and texture

•Crayon after heating
-When you heated up the solid crayons, you caused the crayons to melt. The solid crayons became a liquid and dripped down the paper.
•Crayons after cooling
-As the liquid crayons cooled, they became a solid again. This activity is an example of a reversible change, since the melting was reversed once the crayons had a chance to cool.
•Candles after heating
Candle Wax Combustion
The heat of the flame vaporizes the wax molecules and they react with the oxygen in the air. As wax is consumed, capillary action draws more liquid wax along the wick. As long as the wax doesn't melt away from the flame, the flame will consume it completely and leave no ash or wax residue.
•Candlesaftercooling
Fragrance Leaching
In the days after your candle has cooled, you may sometimes notice that there is a significant amount of liquid on the surface of your candle, as well as a very strong fragrance. This is what we refer to as fragrance leaching, seeping, or bleeding.
