Building a car without a mousetrap i'm desperate

[kailey]

I am supposed to make a car similar to that of a mousetrap car, except without using a mousetrap. I have basic materials and I am completley dumfounded when it comes to making the car "go."

please help me! i am so desperate!

i originally thought that using a car to make the car go would be a good idea but i have no idea how to rig that up.

a fan?

that's actually a really good idea. i hadn't thought of that. i just can't figure out how to rig that up.

use styrofoam (or something equally light), stick a fan on the back. Add wheels. Voila.

idk i think that would be considered "cheating." it's supposed to be some complicated physics contraption.
