I think that Bray should be hot when it has gone through a red filter so that as well as being used to transfer electricity you can use it as a proper laser.
I made a topic like this this morning, but i sugested that bray instantly conducts heat.
+1 to your version it sounds better than mine. good suggestion. also if you don't mind me saying, could the temperatare of bray be the same as the tempurature of the filter?
@PizzaPlatypus yes, so you could make alternate freeze rays and really hot laser beams. I think this should be added it would give BRAY/ARAY more uses and it would also stop people suggesting "laser" which gets annoying. also BRAY should (if this concept was to be added) be invisible to all particles, in other words they shouldn't suddenly stop other particles when they are falling.
