Probably..

I don't know, I think that my previous propellant is clearly out of the equation though, seeing as it's gunpowder. (Yeah, I just now realized this.)

I'll have to think of some more ideas to get it moving..

"Hey, Bobby, what did you guys do today in school?"
"We learned about tinnitus! I'm also full of hot splinters!"

Yeah this was my concern as well. Fucking lol.

So you need to carry a load, plus determine what provides enough thrust to move said load

Correct, but I'm going to put the thrust situation before the load situation.

A battery would result in a nice straight and continuous line.

Seeing as though a homemade battery is easy to make, i'll consult that idea with the rest of the group tomorrow.

What about those CO2 containers? They're compressed and you just have to pop this pin.

Would have been my very first suggestion since i've build a model drag car using these. However, their components must be made so that is out of the question. Unfortunately.

Alright, so it's finally coming together.

The car itself is made out of legos, a common material used in our school.

I found an old lego space vehicle thingy I made a few years ago, and removed all its accessories, so now it's 4 wheels, a base, and 1 rubber wheel in the front, which is going to pull the whole car. (I'll go further into the details.)

The chemical engineer crafted a battery using pennies, aluminum foil, and paper towels, which will be dipped in something with a charge prior to the actual running of the car.

Next to the rubber wheel, there is a lego plate in which I have screwed the motor on to.

Connected to the part of the motor that spins, is a rubber band, which is ALSO wrapped around a secondary wheel, which is ALSO connected to the rubber wheel.

1. The motor spins, makign the rubber band spin on the secondary wheel.

2. The secondary wheel spins, which is locked with a shaft within the rubber wheel.

3. The rubber wheel spins, pulling the whole car due to its traction.

(This pic was taken before the motor was attached.)

better have a decent amount of torque in that little motor

It should be fine, the car itself is actually really light

True.

foofoo, keep us updated on this!  i wana know how it turns out ;-)

ha, it looks like one of those lego NXT creations.

I had an egg drop project in physics.

What i would use is just wood. Preferably balsa

Edit: Also what would work good for a black powder container is a old co2 cartage with a drilled out hole... It would act like a rocket motor

Did you just..drop an egg?

[Tomcat]

from 40 feet yes, onto a moving car.... yes
I was just telling you to use wood for speed

I thought egging was illegal.

[Tomcat]

but the car was a model car

and it was for school soooooooooooooooooooooooo
