Since the vibrations are made by your voice, the sounds your friend hears are your words. Your walkie-talkie is also a great squawker. With your thumb and index finger grasp the dental floss next to the bottom of the cup. Lightly and quickly move your fingers along the floss as far as your arm reaches. A loud squawk should come out of the cup. Keep trying until you get a squawky walkie-talkie. This works because the wax on the dental floss makes your fingers stick briefly as they slip. As your fingers stick and slip along the floss, they set up vibrations.
Tilt the ends of the suitcase up and down. As the peas move from side to side, you'll hear the sound of waves crashing on the beach.
