Did you get a new toy laser for a present this year? Did you get a real laser if you were a really good boy or girl?
Lasers are now cheap and easy to obtain, but there is some caution advised when using them. Using them incorrectly can at minimum be a nuisance to others, and at worst could lead to accidents or death. They also can adversely affect your pets, so don't use them as a pet toy. And if you point them at others or at aircraft, you can be prosecuted.
A good site to review safety and all other things lasers is Sam's Laser FAQ - Laser Safety. Check it out, and be nice using that laser...
