ROLLER COASTER

Today in science we tested roller coasters! Not real ones mini ones. For the track we used a long skinny tube of Styrofoam. And for the cart we used a marble. It worked really good but the hardest part is that you had to loop the Styrofoam and make the marble flip without falling off the track. Some people did it on their first try and some people didn't even get to try because their tube of Styrofoam was really loopy and it kept falling off the track. Lots of people were stuck on the one where you had to put two bumps in it and only two tables got it on the first try! We also had to put one bump in the tube of Styrofoam but that was really easy. And the last thing that we had to do is just slant the Styrofoam and let the marble slide in the cup. This experiment was using lots of gravity and friction! Maybe you could try!
