Quote:I love that site. Learned about it at Snopes.com. Yes, a huge beef about ALL lasers shown in EVERY movie EVER made is that they are ALWAYS shot out as visible even with no dust in the air to deflect photons towards one's eyes! One personal beef is the one time they DO have this bit of thing correct is in a bad bit of engineering, like when someone blows powder across a security laser to expose it. Why would anyone make a security laser in the VISIBLE light spectrum? An infrared beam would never be exposed like that, because it can't be seen! Of course, sometimes it's actually supposed to BE infrared, and they say so, and then they use the same trick and there's visible light! Annoying!

Sometimes you get the scorpion.
