How do you make a alarm bell?

1) First, we checked if our buzzer was working. We did this by connecting the both wires from the buzzer to the sides of the battery.

2) Then we made a security alarm on the box. We placed our buzzer in the box, and made a small hole in the back, and pushed the right side wire of the buzzer through it. Then we fold a small piece of foil to the box.(over the red wire) Then we make a small hole in the foil and bring the red wire out.
