I'm surprised this thread is still running. One of my more infamous nights in the lab was curtesy of "the Tall Blue Lady", a 50 lb cylinder of pharmaceutical grade laughing gas that was delivered by mistake. We jury-rigged an anesthetic delivery system and spent several hours taking turns communing with our inner selves.

How powerful was your laser? (and more to the point, was it green?)

Yes it was green and in the 20 watt range as I recall. Bench made from stuff collected at various Silicon Valley establishments. We had to water cool it to keep it working for any period of time.
