The Can Ripper – Flinn Scientific Canada

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 thecan holding it together, the can will rip apart with just a firm twist. Continue reading

Inside a Soda Can – Hidden Liner – Steve Spangler

You won’t believe what our science guy Steve Spangler found inside a soda can. In fact, it’s inside every soda can and it protects the aluminum from reacting with the soda. Steve takes us inside his lab for a chemistry lesson you won’t forget Continue reading
