So far our project has gone relatively well, we are nearly finished with the general building of our roller coaster, and so far everything works. Last class we were able to secure everything with string so it will not fall over. Inertia has effected our building progress a lot, because a lot of the turns we had planned out on our initial draft were to sharp, and with inertia, the marble would just fly of the edge. We were able to change the turns, so the marble was not effected by inertia. Something that has been really frustrating as we built was the tape keeps coming unstuck, so the tubing will just fall off when we come to work on it the next day, so we have to figure out where it was before, and sometimes it doesn't work right away, so we have to do all the placement experimenting all over again. Something that has been going really well is our loop, because it works every time, and it is able to slow down the marble enough so it doesn't go flying off the track.
