Our teacher, Mr. Calvert, told us that we had to make three switches that worked. A light bulb had to light up when the two pieces of tinfoil touched each other. Mr. Calvert gave us some ideas that we could use but I decided to use my own ideas. My three switches are down below. The first one works when you press down on the circle. The second one works when you pull the stick to make the two pieces of tinfoil touch, then it slings back. My third switch works if you press it down on either side.
