Once play-doh has been inside the machine, it is waste and can't be used again. We're going to separate out the waste while we make the products. The adults will help with that. I'll give several orders, changing colors, you will have to clean out machines and put new play-doh in. Think about ways you can make less waste.
Technicians only use the equipment.
Everybody can help sort waste and talk about ideas for preventing pollution. If you have a bad looking piece of product, or have other colors in it, put into production waste. Give the orders one at a time - wait until all or most groups are done before giving the next order. Reject product that doesn't meet spec. 1. 5 green ropes, as long as the can.
