Leidenfrost Effect plate

this is a peice designed to mimick the experiment first done by the university of bath. it is a sawtoothed plate which when heated to the leidenfrost temperature causes water drops placed on it to fly from one side to the other because of the angle of the surface texture. obviously it should be printed in a metal to survive the high temperature, but i will have it available in all materials. one interesting experiment would be to pu it at a slight angle and have the water run uphill!
