THAT's pretty good. The nickname goes back to the college days. It started out as R-san. One night after some serious partying as I was draped immobile over the recliner - somebody who was in freshman chem said "R-san....more like Argon the fully inert gas". It stuck.
The laser is for my Birdwatching class. I have a Dr. from the local hospital in the class and he came in with a green laser. It is bright enough to be seen during the day and is a great way to point out the birds (which can be quite difficult to locate) to the new class members. Beats trying to point out specific branches 50 feet away in a stand of trees with just a finger and words.....
