2. Subsequent, create a diaphragm for the talking can. Minimize a chunk of wax paper or parchment paper to a measurement barely bigger than the diameter of the can opening.
3. Heart the diaphragm over the opening and safe it firmly with tape across the edges. This diaphragm will act as a vibrating membrane to supply sound.
4. Change the lid on the talking can, guaranteeing a comfortable match.
Creating the Listening Can
1. Repeat the method of eradicating the lid from the opposite can and punching a gap within the heart.
2. As an alternative of making a diaphragm, use a needle or pin to poke a number of small holes across the circumference of the can, close to the opening.
3. These holes will permit sound to enter the can and vibrate a suspended thread or string.
4. Change the lid on the listening can, guaranteeing a comfortable match.
