Can you tell I was asleep during Red Beam Optic Laser Science class that day? Or, actually, I might have just skipped it and gone to the pool. It happened...
I was watching the Keep me a Secret music video (my favorite), and I noticed that the crazy lady appeared to 'see' the beam. Which got me to wondering. Started to think how on Smallville, Clark's eyes do glow red before he heats up. And have seen that effect in the comics, too. And my Science of Superman book didn't cover it...heh...so I just wanted to know.
To sum up: If, while I'm seated next to Superman on that bus, a heavy fog rolls through, THEN I can see the beams?? Because that could easily happen, you know. The windows might be down and we might be travelling through...someplace extremely foggy.
Thanks all for answering. And, no, this has nothing whatsoever to do with a story. I realize that by placing it in fanfic related, I might have given that impression. Honest. I just have too much time on my hands...now I can get to pondering the light saber question. However, if anyone else would like to use this fascinating knowledge for their own fanfic, please feel free.
Consider this a service I am happy to provide.
