Make a Water Motor with a Milk Carton

25 10 2010

Have you been to the Notion of Motion exhibit here at the Museum? Come and explore the turntable, cloud ring machine, and much more anytime before Jan. 23! You can also learn about motion by making this water motor out of a milk carton at home.

Cut off the top of the carton. Next, make an equal size hole in the bottom left-hand corner of each side of the carton. Then cut two small holes near the top of the carton  on opposite sides, so you can attach a handle.  Take a piece of string and tie it to each side of the carton. Finally,  take a second piece of sting and tie it to the middle of the handle.

Hold the carton by the second piece of string that you attached to the middle of the handle. Pour a large glass of water into the carton and watch to see which way it spends. You can cover your first set of holes with tape and make new holes on the right-hand corners or in the middle to experiment.

When observing your water motor remember Isaac Newtons Third Law of Motion, every action has an equal and opposite reaction.

We got the idea to make this water motor at learnhowtosmile.org.
