explanation of how a spoon can sound like a bell

Answer 1

A spoon can sound like a bell”. It is not a riddle. Its science.What Do I Need?ScissorsStringWire hangerTable(or a wall,door)Metal spoonWhat Do I do?With your scissors, cut a piece of string about 3 feet long.Hold the two ends of the string in one hand.The rest of the string will make a loop.Lay the loop over the hook part of the hanger.Push the two ends through the loop, and pull them all the way through the other side.Wrap the loose ends of the string two or three times around the first fingers on each hand.Swing the hanger so it gently bumps against the leg of a table, or against a door. What did it sound like? Probably not much.Now put your hands over the openings of your ears. Hold your hands tight to the sides of your head. Lean over and gently bump the hanger again.Now what does it sound like? Church bells?Chimes?Want to hear what a spoon sounds like? Unwrap your fingers, then pull on the loop end of the string. The whole string will come off the hanger, and you can reloop it around the spoon.Whats going on?You hear sounds when vibrations get inside your ears and stimulate your nerves to send electrical signals to your brain.Suppose, for instance, that you are pounding on a drum. The drumhead starts vibrating. As the drumhead vibrates, it bumps into air molecules and starts them bouncing to and fro. Those bouncing air molecules bump into other air molecules and start them moving. This chain reaction of moving air molecules carries sound through the air in a series of pulsating pressure waves that we call sound.Sound waves carry vibrations from the drum into your ears. Inside your ear, moving air molecules push on your eardrum and start it vibrating. Your eardrum, in turn, pushes on the bones of your middle ear, the tiniest bones in your body. These bones act like a set of levers, pushing against the thin membrane that covers the opening to your inner ear.The movement of this membrane makes pressure waves in the fluid inside the cochlea, where cells with tiny sensing hairs transform the waves into electrical signals. These electrical signals travel along the auditory nerve to your brain. When these electrical signals reach your brain, you hear a sound-the beat of a drum.When the string is around your own head, the sound can take a more direct route to your ears. Rather than traveling through the air, the vibration scan travel through your hands and through the bone of your skull directly to the fluid inside your cochlea in your inner ear. Instead of traveling from solid to air and back to solid, the vibrations move from one solid(the string) to another (your bones), and then into the fluid of your cochlea. As a result, you hear a bell sound
