Because the box it came in said "Laser-etched Glassware" lmfaoooo

But, I have worked in the engineering industry, which is increasingly using (bad grammar - same excuse as you lol) lasers in the production thing...

start again:

Lasers are fast becoming the norm in the engineering industry, of which I have had some experience. From that experience, I have gained the knowledge that lasers are extremely versatile - they can cut sheet steel of up to 8mm in thickness, to a tolerance of 0.001mm!
My father works in Argon Gas Emission Spectrometry (which also employs lasers), and thus have gain a little knowledge about lasers there too.

But mainly I know, because it said: "Laser-etched Glassware", on the box hehehe
RESiNATE Reviewed by RESiNATE on . Insomnia I've got insomnia :( I wonder how many people have actually walked this Earth, since time began... If there are 6.5Billion people on this planet now, and a person is born every 2 seconds, and someone dies at the same time, it shouldn't be too hard to figure out...should it? How long has this planet been habitable? Multiply that by 6.5Billion, and the answer should be something around that figure, yeah? But, of course there hasn't always been 6.5Billion people alive at any one time, Rating: 5
