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

To build a marble roller coaster, you will need:

*Foam pipe insulation
*Razor knife works best
*Electrical tape or duct tape or masking tape
<p><em><strong>you could also make it at a sharper angle so more loops or hills could be involved...</strong></em></p>
<p>Eat it</p>
Cool project. Try to light your photos a bit better next time, but this build looks like a lot of fun. Definitely a precursor to permanently affixing the track to the wall. Also, can the cars manage that loop?
Ok. Thank you for the input. The marbles can make the loop if if is the right size and if the marble is going fast enough.
