We were asked to build motors the other day. We had one day to gather up all the materials needed to build a motor. Luckily, we were able to gather all the materials even though some of them were hard to get.
When we started building the motor, we were given 30 minutes to hammer the 4 four-inch nails into the wood. The nails had to be 2-3cm apart in width and 5-6 cm apart in length. We then sanded the pop can all the way to the point where both sides were silver. Our first problem popped up when we were trying to fit the axel into the cork. Our cork was a bit bigger than the other corks other people had so it took longer to get the axel in. The cork was also a bit rubbery which didn't help us. The second problem with the cork came up right after the first. the copper coil wasn't holding onto the cork tightly enough, and we spent a long time trying to get it to stick. In the end, our motor ended up as a fail. D=
