Description

Adding vinegar to a cup with steel wool to observe a reaction generating heat (note the wool needs to be removed from the vinegar then squeezed dry and left compressed) Oxidation then occurs and the temperature rises. (Leaving steel wool in the vinegar only evaporates vinegar temperature remains same). Have a control by dipping steel wool in water alone and squeeze out next to the wool that has been in vinegar - compare the two. The lump that has been in water alone neither heats up nor dis-colours.
