That balloon one is interesting... and what happened to the mirror? It looked like it turned black and then back to a reflective surface as it cooled... That's pretty intense. I wish my X105 could do that.
So I get that at 10.6µm , the beam doesn't get reflected by the mirror?Or doesn't even reach the mirror as the glass is totaly opaque to 10.6µm wavelength laser?
How about cutting a floppy disk or a cd case in half next? ;D
