If your appetite for lasers has been whetted — and your fear of bodily injury and blindness hasn't yet intervened — The How To Guy has a detailed guide to making a burning laser in the body of a flashlight. It's a step-by-step guide with detailed photos for each stage.
As the author reminds you: Be careful. Don't use this laser to play with your pets. And do not look into your laser beam!
At least, not with your remaining eye.
