  one with 30 mL of fresh Cola, the other with 30 mL stale Cola, matches.
* Close the two vials, shake them and leave them for one minute with the stoppers slightly loosened.
* Left: Dip a burning match into the bottle with the stale Cola.
* Right: Dip a burning match into the bottle with the fresh Cola.
