Ozonolysis
Description: A sidearm flask is filled with oxygen via air displacement and fitted with a copper wire and an aluminum foil cover attached to ground. A tesla coil is used to apply high voltage to the system, producing ozone in the flask. Then a wire frame with a rubber band is placed in the flask and the rubber is broken down by the ozone gas in the flask.
