VillageIdiot said:Main things my friends/family have asked me about lasers:
-Can you colour the lens on the front to make it a different colour?
-Can you melt steel?
-Does it cause cancer?
They also have no idea what divergance is. They seem to have the idea that it keeps its beam diameter indefinitely.
Lol my family are the same, I was sitting shining my 30mW laser at my skin and they were like STOP your gonna end up with skin cancer, and I was like no, its normal light, so they argued back by saying that you get skin cancer from the light from the sun, so I had to explain that was because of UV rays and how they were different. I also had to explain that the colour could not be changed to many people.
