Last week Isabella and I made a prank handshake. We went around the room to give handshakes to everyone and when they pressed the button you could feel it moving on your arm. The noise sounded like a car horn. It was very annoying when everyone made it and kept pressing the button. We used a battery, a wire that connects to the battery, a mainboard, a wire, a button, another wire, and a buzzer.
