May 28th 2014, we made a lot of progress today. I feel good about our progress so far. We made the track go around the piece of cardboard. We attached a loop to the burj. Inertia affected our roller coaster negatively, because there was a part that the ball was supposed to make a turn and go up a loop, but it kept going instead of turning. We had to cut toilet paper rolls in half and tape them under the tuber so the marble doesn't fly off the side.
