Method of producing sliding film on made-up surface for driver training

摘要

A method of producing a slippery film on a made-up surface comprises spreading approximately 5 g polyacrylate absorber per square cm over the surface and spraying 1.5 litres of water per square cm over it. Preferably, the absorber is a starch-containing sodium polyacrylate. The film can be removed by spreading Na acetate, lime or salt on the film and then sweeping it away.
