Why does tin foil makes so much noise when you touch it?
In: Physics
Tinfoil (really aluminium foil) is both hard and weak. It’s a rigid material because aluminium is rigid. This makes it good for making sounds, as it can vibrate rather than flopping like fabric. However, because it’s rolled very thin, it’s easy for us to bend it when we move it. Each time you move it, it’s like loads of tiny cymbals being hit.
