Identify the problem -We are trying to build the quickest, lightest, and most aerodynamic dragster possible.

- I have thought maybe making a long narrow dragster with a place in the back in it for the CO2 can.
- Another idea is to have a car that is low to the ground and curves in at the sides to help with aerodynamics.
- I was also thinking as I was looking at these things to have a curved top to help with downforce so it doesn't go flying off.

Criteria - Some criteria is:
Weight- How heavy it is
Speed- How fast it goes on the track
Balance- Is it steady when placed flat on the ground?
Research - I have started researching the CO2 dragster and found these website very helpful (I searched CO2 dragster in google)

"CO2 Dragster Dynamics - HowStuffWorks." HowStuffWorks. N.p., n.d. Web. 28 Apr. 2015.
Things worth researching:
-Basic aerodynamic principles/forces

-How do aerodynamics impact automobiles

#1
This right here is a simple CO2 dragster shape and consist of nothing to fancy. It has a long narrow nose and is blade like at the nose to help with aerodynamics and goes in and out in the middle to help with aerodynamics.

This Idea is a flat and narrow car. Its aerodynamics are very solid and the width of it should keep it on the ground.

Idea Matrix:
Summary:
I will go with drawing #1. We will make the nose long and narrow with a dip in the middle and sides. The back wheels will be larger than the front providing more traction. I t will be overall very steady and pretty fast I think.
