The Design Process

The Design Process


Materials

• Wood
• Cardboard
• Straws
• CD

How we made it:

We had a basic idea of just a block of wood and four wheels, but we quickly realized a block of wood would be WAY to heavy so we traded in for cardboard. We first took a square piece of cardboard and taped 2 straws at the end. We then attached 4 CDs to act as wheels. And then we had the base of our balloon car. (Pic. 1, below)

We then realized that we could even use a lighter material than cardboard so we swapped in for a thin plastic. We also created a nozzle for the balloon to fit snuggle and take off! (Pic. 2, below)

Total Amount spent:

We have spent no money so far making this because we have used household stuff.

Outside sources:

We haven't looked up any information on balloon cars, because Johnny is good with building and we had a pretty good idea of what we wanted to make.
