Atempt IV.I

Our first try outside. it passed the 5m mark but then hit the wall. So it is a success.
After this run, we had some difficulties with the wind that we had not accounted for. So, we had to move our testing area inside. A video will be uploaded when I can get it to work on my computer.

Attempt IV (!!!SUCCESS!!!)

This was our fourth and (thankfully) final design!

(sorry for these pictures... you may have to turn your head 90 degrees to see it)



So we didn't change anything major (as stated before) but we used Styrofoam balls for the wheels. Also because we popped our previous balloon (for reasons unknown) we now have a BLUE BALLOON.

For those of you wondering "why is there a candle positioned on the front????"
Answer: We're going to light it up!!! (It's there to counteract the weight of the balloon at the back...)

Attempt III

This is our third design and it worked!! YAY!!!!

This design of car went approximately 8 m, however, what stopped further construction of the vehicle was the fact that Mr. P didn't allow the usage of TOY CAR WHEELS!!!

So it's back to the drawing board... however, we're not planning on changing anything major about the car, just the wheels.

We'll keep you posted on anything new...

Attempt II

Our second attempt was based on the theory that the air from the balloon would turn the wheels and move the car.


We tried blowing the air on the wheel alone but that didn't work, so we tried adding Styrofoam paddle wheel inserts. That design also didn't work.
We realize that this design did not fulfill the needed requirements to succeed as a car because there was too much friction acting on the wheels which prohibited the movement of the vehicle. 

Attempt I

This was our first attempt:


Reasons explaining as to why our first attempt at constructing the balloon car failed are:
1. The wheels weren't centered
2. We had leaks in the rod guiding the air out of the balloon
3. We couldn't keep the balloon effectively off the floor, therefore the balloon prevented the car from progressing forward
