CO2 Dragster Challenge
Dragster #5
Improvements
- Wheels could be adjusted
for a tighter fit
Dragster #5
What is aesthetics?
The principles concerned with the appearance and the appeasement value that is weighed by the design and structure of a model or artwork.
Dragster #3
Positives
Dragster # 3 Pictures
- It has an awesome paint job
- It rolls smoothly
- Had an unique design
- Small dragster for speed
- Has a creative and neat paint job
- Slim design for speed
- Curved for better aerodynamics
- Wheels are smooth
Dragster #2 Pictures
- rough sanding, but slim
- Bigger end will slow it down
Blue Prints
- Creative painting idea
- Random holes in the top and it almost touches the ground
Dragster #5 Pictures
The design was an attempt to make an
aerodynamic car.
The shape was a design that was meant to reduce profile exposed to head winds
- Not curved
Video
- Curved surface and neat painting
Weight and Aesthetic
- Uneven cutting (left side is more curved in then the other side)
- Loose wheels

Dragster #2
Was too big- Would like to have used
1/2- 3/4 of the wood instead of using
the entire length of the wood
Time was a determining factor- We would have liked to make our car rounder than it was.
Repainted several times due to dripping errors
Speed- 32 mph
Time- 1.524 seconds
Reaction Time- .146 seconds
Positives
Construct and design a CO2
car to have the fastest speed and have a pleasurable appearance.
Weight- 1.1 kilograms (1100 grams)
Dimensions Weight- 35.24 oz
We used a thick coat of paint to obtain a shiny appearance. Then by using a simple aerodynamic design and a choice of complementary colors, the car stood out and gave it an elegant and unique appearance.
Day 1- Drilled axle holes, cut rough frameworks,
and gave a rough sanding
Day 2- Sanded the entire day
Day 3- Spray painted the car
Day 4- Cut the wheel axles and added second
layer of paint
Day 5- Added wheels and finished painting
- The car rolls smoothly
- Has a small and light design, so the car will go faster

Dragster #2
Improvement
- The paint job was not well done
- Sanding was done to a minimal
- Had an uneven surface
- Random holes in the front
- Aerodynamic design was questionable
Dragster #3
Improvement
- Front wheels are wobbly
- Unsymmetrical base design
- Extra drag due to straightedges- could use a rounder design
