Have you ever seen someone make smoke rings? They have the scientific name vortices and are related to other vortices like the whirl pool in your tub or sink and even tornados. They look neat and they have some very interesting scientific properties, but science smoking is very bad for you, it seems impossible to make them. Here’s a way to make smoke rings without smoking.

Take a cardboard box (a shoe box work well) that is open on one side only. Cover the open side with some plastic wrap (like saran wrap) and tape it on well. On the opposite side of the box cut a round hole 3 or 4 inches across. You now have smoke ring maker so it’s time to load it with smoke. This part can be dangerous so please ask an adult to help. There are many ways to get smoke into your smoke ring maker; you can put a piece of dry ice into the machine (don’t touch dry ice with your skin, it is very, very cold), you can use some baby powder, if it is fine enough, or you can use smoke (but be careful that you don’t light your box on fire). You don’t need much smoke to make many rings.
