Can Ripper

Show the power of chemistry by tearing apart an aluminum soda can with little effort. Just score the inside of a soda can to break the plastic lining, add some copper(II) chloride and water, and sit back—chemistry will do the rest. The single replacement reaction of aluminum metal with copper(II) ions “dissolves” the aluminum from the inside out. With only the paint on the outside of the can holding it together, the can will rip apart with just a firm twist.
