Materials

3. Test 1: The car didn’t fit down the ramp so we had to shorten the rods Test 2: It needed to be a little heavier so we added some chained fabric Test 3: It went through the ramp and rolled smoothly and we didn’t have to change anything Test 4: Didn’t need to change anything about the car
Functionality

4. Test 1: The front poof ball lessened the damage impact and bounced off and we didn’t need to change anything Test 2: Curvature of upper neck of the bottle allowed for the impact to be concentrated in that spot, lessening possible damage done to egg. We had to make upper body heavier. Test 3: Outer rim of wheel allowed for wheel to keep rotating after impact. We didn’t need to change anything.
