School Chemistry Project
Foofoojack:
So around a month ago, my whole chemistry class was assigned a fairly large project - the whole class being split up in a number of independent groups.
So a group of me and 4 other people, have to construct a chemical reaction causing propellant, to propel a car.
The thing is, each person has a different job in the group, we have:
* 2 group managers.
* 1 chemical engineer.
* 1 graphical design engineer.
* 1 mechanical engineer.
I have the job of the mechanical engineer, the one who physically builds the car.
Here are some of the physical car requirements:
* Must fit into a shoebox.
* Must be less than 2 kilograms total mass.
* CANNOT be constructed using any pre-existing model car or kit car.
* Must travel 10 meters in a straight-as-possible line.
* Must be able to carry 500mL of water or 500 grams of mass.
Furthermore, the car is going to be propelled by a black powder, consisting of the formulaic equation:
2 KNO3 + S + 3 C ---> K2S + N2 + 3 CO2
Seeing as though it is a black powder, I'm lost at ideas of the physical car, the shape, form, product, material, of how it will be built.
Got any good ideas on how I could put it together? (Please try to be as serious as possible, and keep to only posting if you know what you're talking about.)
FYI, my father and step-father both work in the mechanical industry, so I have access to a lot of material.
Thanks!
(There may be rewards for very contributing people!)

My friend made an outer shell of his car with lego blocks and some wood + wood glue, but he made a compartment for a co2 cartridge. You could try the lego idea, make it black and snazzy and somewhat aerodynamic.

Wood is still a reputable way to go. skeletonize that shit
Foofoojack:
Wood and/or legos sounds pretty useful, but how would it be crafted to hold the black sulfuric powder?
Where would the powder go? What would hold it? What would make it secure?

depends on your method of propulsion. black powder burns pretty quick.
How will you be using the black powder to propel your vehicle?
