Our first idea was to make a paper Lamborghini. We looked on many websites to find ways to make an origami-type Lamborghini. All of the instructional videos that we found were at least an hour-and-a-half, or did not even look like a car. As we got to school I had the idea to look up paper models of Lamborghinis, the kind where it has the dotted lines and you cut it out, fold it where it says to, and tape it together. We printed it out and we could not get it big enough on a standard-sized piece of printer paper. There were five basic shapes on the model so we just decided to take five pieces of paper and draw the shapes much bigger and duplicate the design. After we drew the design and cut it all out we decided to cut out pieces of cardboard the same shape and put it behind the paper so it was more stable and added some weight. For our balloon, we put a hole in the back of the car that we could put a straw through, and taped the balloon to the straw. We taped the straw up on the back part of the car so when we blew up the balloon it would go straight up. Our wheel idea came to mind when I was drawing out an idea for our car. I was using a blue highlighter, accidentally dropped it, and we discovered how fast it rolled. We decided to try to pop out the center part of the highlighter so we could put a piece of wire through the center through the two ends and hook the wire through the bottom part of the sides of the car. We were going to use two highlighters, one in the front and one in the back, instead of “4 wheels”. However, we could not get the center out of the highlighters. We went “dumpster diving” around the school and ending up getting pop caps from Ms. Chambers.

Since our idea was to use highlighters and the wire, once we hammered a hold through each of the caps, we couldn’t figure out how to make them turn because we did not have a good axle. We tried to use just a straw for the axle and that did not work. We then tried to compact the...
