What fun project can I do with around 300 Liconix high powered laser lenses Collimator ,optic lenses, Optic Filter..etc

Old Neighbor of mine was a Senior Laser Technician for Liconix about 10-15 years ago probably still works there.

Anyhow he always would always be working on lasers Argon, Helium, Krypton, and his classic cars and overtime his family became sort of family to me. I would watch in awe as he worked trying to learn as much as possible. So I would help him work on his cars or Fix a PC for him here and there or take care of his son. I was only 13 at the time, but he was nice enough to give me a couple lasers for helping that his work was going to discard, some helium, Argon. I had to give the Argon back though because he sold his house and was moving to a better neighborhood. Plus it kept blowing the fuses in my parents'house from the power load. PGE was getting angry cause for some reason the street light sensors in my neighborhood were somehow getting burned out all the time *shrug* I don't know how and had to keep repairing them.

Before he left he gave me some extra tubes for when my others eventually died. Most helium and tons of lenses of various sizes which are all tucked away in a box. In my dad's Garage of Death yeah he's a pack rat. But I found a couple of the lenses when I came to visit that I had sitting around the house and thought to myself time to dig the box out, so I'm slowly digging my way to it. Just don't know what fun project to do with all of it other than making a Laser Beam of doom or putting them on Sharks with fricken laser beams attached to their heads I also have a Fresnel lens from a 45 inch rear projection TV. Any Idea what fun project I should make with all of it ?

I bet it would make one hell of a laser pointer for my Celestron GPS-GOTO C11 Telescope haha.

Thanks for any idea's.

Doom ray for the fresnel lens, search the doom ray here on 'ibles, using a fresnel lens, a simple frame and the sun... As for the lenses you could well be able to make some rather interesting light shows using them, or make a laser shark or two...
