Alright, so I managed to finish building the mousetrap vehicle, but with one significant problem: it doesn't go backward.
Which is odd. The winding is correct (clockwise -> once around pin -> counter clockwise), but when I release the lever arm it simply stops halfway. When I push the lever arm forward to simulate how the vehicle would move, it goes forward a bit more then starts moving backward, indicating the problem is perhaps in the mousetrap itself? Has anyone run into a similar issue?
Events: Remote Sensing, Chem. Lab, It's About Time, Dynamic Planet, Mission Possible, Env. Chem. The latter two I found out I had to do 4 weeks before Regionals. Fun, fun, fun.
