Mar 4 2011 (FINAL)
I (Alicia) still won't give up.
Originally we accomplished getting 51 floor tiles but the highest is at 74 for this year. In my opinion, the ratio between these two numbers is too great. So I am still changing, redoing and doing anything I can to try and get a further distance. We have nothing to loose so why not try until the very end?
Since the rest of my group hasn't completely given up, it's up to me. I decided that our car was missing a lot of elements that could really help it such as mechanical advantage... So I stubbornly decided to take out the CDs we used as the back wheels and replace them with records. After gluing it and assembling everything, it was too heavy!
Mr. Smith helped me remove material/mass from the wheels by drilling holes into them. Originally one record weighed 105.8 grammes, by putting in holes, it now weighs 89.2. That is 16.6 grammes saved!
Monday is now the moment of truth and our last shot at a larger distance. Hopefully Alicia and her perseverance will make it through.
