plasma does full damage to glitter boys. it is very different than lasers.

ANY finely polished mirror surface can refract up to 90% of a lasers' energy...except X-ray lasers (but again, we won't go into that territory).
So short answer long; what the hell are they teaching in science classes now a days? In GRADE 3 I had a basic concept of Laser Vs. Plasma. By Grade 6 I knew different natural occuring plasma types (Ball lightning, aurora borealis, solar prominances).
Tell these players to get a clue.
Or go to a REAL school, whatever comes first.
Think your being a bit harsh there mate.
Not everyone has the same intrest-concentration, after all those more intrested in biology will think plasma refers to the liquid that transports haemogoblins around; not super-heated ionized gas.

It's basic science education in Grade 6 in Ontario. and we have the WORST public education in all Canada. No..not harsh at all dude.
Ah but not everyone is from Canada, it's way to cold

Plasma is not just "superheated gas". It's an entirely different physical state of matter, and one that's more highly energized than gas. When you heat stuff to the stage where it becomes a plasma, you've put so much energy into it that all molecular bonds have broken down, and the free atoms floating around have had some or all of their outermost shell of electrons stripped away. Basically what you've got is a superheated sea of ionized atoms and free electrons, and it's a very angry state of matter indeed. It's electrically conductive, chemically reactive as all get-out, has momentum if its moving at high speeds because it is indeed just ordinary matter, and of course is as hot as buggery.
But yeah, apart from that minor correction, everyone's right on the money about how it's completely different from lasers. Lasers are coherent, incredibly concentrated beams of light. Plasma is what happens when you cook matter so hot that it doesn't just melt into a liquid or boil into a gas, it goes right through gas and into the next stage after that.
