Magnet Car

Sara and I worked together on the magnet car and it is working really well.  It is two long lego pieces with a one of those black long straight pieces as the axis.  We have two small wheels on the back so they don't wiegh the back down and we have two big wheels on the front to keep all the acceleration going.  Our car is very easily rolled which is good.  For our magnet we took a U shaped one and duck taped it to the top.  We then took a ruler and put two U shaped magnets on the end of it that make the other one repel.  This works really well.  Our first time we got a minute and 18 seconds but we cut it down to just 33 seconds.  Also one time we just went one way and it was only 13 seconds.  One problem with this is that some of the time the magnets get messed up and connect which does cause some issues but hopefully all will be ok!
