Your next design is to make a device (probably a car) that does the following:
a) starts with a specific starting mechanism (can sit by itself and starts when you use some kind of switch.)
b) travels "exactly" 2 meters and then stops.
c) at the end of two meters, it pops a balloon. The balloon will be attached to a rigid object, so that there is resistance against it (making it easier to pop.)
This project will be scored according to a rubric system. (to be announced later.)
You will also need to hand in some calculations, namely the torque of one of the mechanisms.
