I like the string trick... In the 70s, before they really had laws for it, I strang all the doors to the fire alarms. It wasn't a prank really, more a science experiment. Like dropping a skunk in the central heating system, setting the head cheerleaders hairspray on fire... on her head...
Yes, the 10mm is too small for my ass, I have an 80mm that might work. :D
'Crystal' may not be an accurate term. I didn't purchase the 10mm, probably leaded glass. Actual crystals of any good diameter are hard to find. Forget Swarovski crystals... Expensive glass. The term crystal...
In a fixed position, unless you're moving, crystals are boring. I noticed 10 to 60mm faceted spheres for cabinet doors at Home Depot. Mount that crystal on a winded up musicbox motor with a fixed laser... and presto! Laser jewels everywhere!
Sorry if I've missed the discussions up to this point; however may a static field around the lens [or lenses] amplify or modulate the frequency of the beam?
Over the course of time I hope to conduct several experiments using crystals.
This is a 50mw green & 20mw red directed at a 10mm faceted sphere.

Typically most would come to the same conclusion.... I shot a robin with a BB-gun as a kid, watched it fall. Worse thing I ever felt as a kid, but it taught me to respect birds later.
Perhaps listing the number he has available will lead his competition to his wholesalers. He may be low profile about things due to local restrictions.
This arrived the 17th, yesterday USPS in a felt covered gift box with a complimentary 5mW red keychain pointer. The 50mW green laser definitely stands up to its reviews. I don't have a tester, but a nice powerful beam!
Out of the box, beamshot:

This may help explain the image of the guy with the dog. I hadn't realized many here may never have seen the movie "Silence of the Lamb." About a psychopathic psychiatrist name Hannibal Lector who cannibalizes his victims ...is asked to help solve murders committed by the guy with the dog...
While designing an Alien Switchboard for our [signature] site, it occurred to me that aliens have no clear way of reaching us.
Therefore in the interest of science and fun! What internet address or button can one push to reach us all?
