Hey there, how is life going? Well today we are suppose to do a write up on test day so here we go. Our car worked pretty good but it wasn't really reliable because our string kept breaking, and it wouldn't keep going the same distance, and it wouldn't keep going straight. We had one wheel on the front and it was mounted off to the side, and it was going straight but then it had a malfunction. It ended up going off to the right so we stuck another wheel on the other front side and it went fairly straight but not near as far. The material we used were paint sticks, cds, wheels off a toy, and a steel bar for an axle. We glued it all together with a hot glue gun. It pretty much follows our original design. It is a fairly safe vehicle to operate other than the string breaking and snapping your fingers. It is rather easily to operate, one person can do it. We ended up getting it to travel fairly straight, but it was only going like 6 meters. It was going 11.5 to 12 meters before test day, but it didn't want to work.
