In class, we started to make circuits. I am making mine from cardboard, tin foil, popsicle sticks, and a rubber band. To make it work, you have to push down the popsicle stick so that the tin foil on the bottom of it touches the tin foil on the surface of the cardboard. I used scroll saws to cut my cardboard and then hot glue guns to get it to stay in place. The rubber band holds the popsicle stick up when you are not pushing the popsicle stick down. I was very happy with the end product. We will be testing them out on Friday, the 21st.
