"Things You Wouldn't Know If We Didn't Blog Intermittently."
NOW we KNOW!What a Lightsaber really sounds like.
I'd be kinda concerned about the residue going into the air.
You can see them holding a vacuum cleaner tip by the laser working in a feeble attempt to catch the harmful residue.
THIS--this is why we who write SF have such a hard time keeping ahead of technology!This is actually a problem for many genres, and may be the reason we see so many period novels these days (set in the 1920's, 30's, earlier, etc.). In the SF world, Steampunk is manageable, true future SF gets harder and harder.As to the laser: Wonder how it would do on graffiti? Or, for that matter, a pile of dog poop on the lawn?Lurker111
