Use carbon dioxide and oxygen gases to extinguish and ignite fire.
There’s a lot of chemistry behind the simple lighting or extinguishing of a flame. Would you believe us if we told you that you could extinguish a flame just by placing it partway into a graduated cylinder? What if we told you that you could relight the fire without a match or lighter? Both propositions seem unlikely, if not downright impossible. With the Flame Light Relight experiment, however, you’ll see how a few household items can mix together and create a fire-based experience you have to see to believe.
