In this Education video tutorial you will learn how to make smoke or fog rings with a rubbish bin. This is really very easy and simple to do and takes practically no time. For this you will need a smoke machine like the ones used in night clubs, a rubbish bin, piece of oil cloth and a strap. Cut out the bottom of the bin and cover the top of the bin with the oil cloth and strap it up. When you push on the oil cloth, air will go out of the hole at the bottom. Now fill the bin with smoke from the smoke machine. Holding the bin horizontally hit on the oil cloth. As air goes out of the bin, it will make rings of smoke shoot out.
