I used to have a sweet laser pointer in the late 90's, it took a few AA batteries and looked like a long pen, had a bright red beam and it could shine clear across the corn field to my neighbors house. (lived in the country then) $30 at Costco. Worth every penny. However, you could never see the beam unless it was foggy or dusty out.
The best was pulling it out in front of a cat and running it along the ground or up a tree, they just wanna grab that laser dot but they can never quite reach it, haha. Made 'em spin around in circles and stuff.
But then I lost it and I still don't know where it is. So this website is quite intriguing, especially green & blue colored lasers.
