I have an idea thats simular but different. Pipe, [PIPE] would work like this: when selected and clicked on a element in the game, it would coat that element with metal to create a pipe. imagine drawing a line of water in pause and the clicking on it with [PIPE] to coat it. Im not sure if this is really possible to make in the powder toy but lots of the stuff in the powder toy surprized me when i first played it.
