Mousetrap car help?

Question

I`m doing a project for my physics/chemistry class for a mousetrap car..It`s supposed to be simple, since we`re only in middle school, and I can`t use any manufactured items (like Toy car wheels, lego wheels, etc.) or I`m just allowed to use things that I can find in my drawer or around the house.
Does anyone have any tips? Or help how to build a good one? o_o; All I have is a mousetrap..It needs to go at least 1-2m, have the body shape larger than the trap, and added material to produce traction to all wheels. :x

Please help? ^^;

Pictures do help as well, but I already skimmed through a lot of websites I looked up on Google/Yahoo...

Thank you. :D

Oh, and yes, I sort of prefer it not so big in size.. o___o;;; Something I can carry to school in my hand.

Answer 1

when i did my mouse trap car for high school, i used meat and cheese platter plates for the back wheels and cd's for front.. The bigger the back wheels the longer it will go.

for the body construction, i used model grade plywood, like what you use to make those little hand held gliders out of.

make the front of the car to a point for better wind resistant.

as for traction on the wheels, i took the wide rubber bands, cut them and super glued them to the wheels.

now, you will need to get an extender for the mousetrap leverl in order for it reach the length of the car (the longer the car the farther it will go as well.)

all this should make you the best car in the class.

Use CD discs front and rear. in case you like a smaller front wheel use those mini discs. you will desire to purchase axle/hub adapters on the 'internet' very few interest shops would have them yet would desire to have the means to order for you. The fishing line in simple terms wraps around the rear axle.
