When I was in 8th grade I wanted nothing more than to build a ruby laser. I made tons of designs for applications and researched it many hours every day. +1 for sharing

I also had a interest in ruby lasers in junior high. We had a "how it works" project and I chose ruby lasers as my topic.

That was an insightful video. The details are way over my head but nice to watch nonetheless.
