i know many of you have play'd with cornstarch as a kid and you know how it works right? well in powder toy cornstarch would work just like that! it will be a liquid untill its hit with force then it will be a solid for a second then the item will sink! sorry if this has ben said before
very true, someone just needs motivation to make it, and starch doesn't sound or look as cool as cold flame. But it would be different because there is no liquid that goes solid under pressure.
