How Smoke Alarms Work

One of our readers, William Hatfield, sent me a link to this very cool explanation of how smoke alarms work. It is a bit technical at times but I think most all will be able to grasp the general idea.

The video was done by a college professor Mr. Bill Hammack (a.k.a The Engineer Guy). You can find more of his stuff on his web site: The Engineer Guy

Stay Safe,
