Test 2 for Design 3

Test 2-

Hypothesis:
If Cd's are used for the wheels, then the vehicle will follow a straight path.

Procedure:

1. Insert pen through 2 Cd's.
2. Hot glue the Cd's to each side evenly.
3. Glue pen and Cd (wheel and axle) to vehicle base.
4. Repeat steps 1-3 for the other set of wheels.

Results:
When the car was realeased, the Cd's allowed the vehicle to move in a straight path. Also, the Cd's helped the vehicle move faster and smoother.

Conclusion:
The hypothesis was proven correct. The Cd's affected the car by allowing it to move in a straight, smooth, and fast path. This also follows the rules that the vehicle must stay in a 2 tile wide path. Overall, the Cd's had a postive impact on the vehicle.
