Marble roller coasters are fun and easy to build. This project has a few things that help this work. One of them is one of Newton's Laws of Motion that says that an object in motion will stay in motion and an object in rest will stay in rest. Gravity also make this work. This is a fun project that kids will love and can also learn some science!
Step 1: buy the stuff
