Hello once again! Here we will explore some advanced things about the LASERS in powder toy. So, let us start! Our lasers are made with PHOT, and as we know, the real photons are influenced by substance inside which this photon is. Powder toy can partially emulate this process. At the (1), you can see as the GLAS here influences PHOT - decomposing it into the full spectre - from red to blue. In (1a) you can see, that - among decomposing - glass allows you to change PHOT direction or even spread them into multiple beams. But glass is not the only material that can influence photons. All materials WILL change PHOT's direction. The best suited for it (just because it will not be melt by lasers high temperature - this is the only reason) is DMND.The real physical rule says that light's (which - in its turn consists of photons) angle of falling onto surface equals its angle of reflection. But in PT this works a bit... weird. But anyway, you may use diamond to reflect laser beams as I made in (2) and (8). In the (3), you can see that LCRY can be used as a gate for photons. When it is turned off, it behaves as any regular material, but when you turn it on it allows photons to move inside itself freeley. if you need to change your laser's color< you will need to use FILT. The filter changes all photons inside itself into its own color, which in its turn is based on its temperature - from blue (cold) to red (hot). You can see this on (4) and (5). Also, you may note that photons passing the portal are NOT maintaining its direction though saving its temperature and color. And the last one thing: photons passing the INVS are not just changing their colors - they are TURNED INTO NEUTRONS. This may be useful for some kinds of reactors. That' all, gentlemen!
