So, for physics, I had to make a mousetrap car that has to go at least meters. I made one, and I've run into a major snag. The car goes ~1-3 meters, and that's sporadically. I know this car can go ~5 meters consistently, as my brother has tested this car. Since he's left for college, he can't really give explicit instructions on how he did it, and I'm stuck wondering how he did it. So, the question is, what am I doing wrong that prevents the car from reaching my desired distance?
What I did:
1. Wind up the string into one tight layer with no overlapping.
2. Wind up the string again into a second more loose layer.
3. Tie the string to the mouse trap, making the string wound between the axel and tied to the mouse trap as tight as possible.
4. Set mouse trap.
5. Trigger it.
