BRING SCIENCE HOME | Gravity-Powered Sorting Machine | Want to sort through objects of different sizes quickly? Engineer a simple machine to do it for you! Credit: George Retseck | Have you ever used a coin-sorting machine to separate pennies, nickels, dimes and quarters? When you need to separate things that are all mixed together, using a machine can be much faster than picking them apart by hand. In this project you will build a machine that can automatically separate two different size marbles—powered by nothing but gravity! | | | |
