Technology #6

Today I started working on my second switch. It is a little simpler than my first switch but it still works. This switch is a see-saw. The part where people normally sit is covered in tinfoil. The board that the see-saw is on on is also covered in tin foil. When you move the see-saw up and down, both tin foils touch. When connected to a circuit, the light bulb lights up.
