I cant found it MERCURY (or liquid metal if you want elements without peroids table, but you have to change temperatures of vapor and solidify) Liquid, conductive. Can vapor 356,73~=357 and solidify -38,83 ~=-39
Now that I think about it, the powder toy needs nothing more. Nothing but sound! I know this has probably been suggested before, but I'm not talking about sounds for explosions and other phenomena. I'm talking about an element which gives a certain frequency (dependant upon how much of it there is) sound when electricity traveling through a wire touches it (like LCRY). This could be used in electronics as an indicator or in other saves to make musical instruments. At least it's more usefull than chocolate.
i don't know anything about coding but is it even possible to implement sound into powder toy.. i mean none of the countless other sand games have sound and have been out for many years without any..
MEAT, BACTERIA, POISON (kills stickman if he goes in it) and acid gas, poison gas, powder coal, air, wall thet only lets things over certain temperature through and vice versa, and I agree that we need sound, clone that only clones things over certain temperature + vice versa, powderry goo, straight line lightning, something that burns but takes ages to heat up, anti fire , slightly cool fire, different eraser types eg. wood eraser. Tar (gloopy hot liquid) string, paper, different types of metal, mercury etc.
