Today I started making my first switch. It is a board covered in tin foil and then there are two popsicle sticks on the sides. There is is a popsicle stick hot glued on top of both the popsicle sticks, connecting them. There is also a rubber band glued on to the popsicle stick and the board. When you push the board down, then both of the tin foils touch and when connected to the circuit, the light bulb lights up.
