Stones emit noise.... Here's an interesting fact - the sound rocks make can vary depending on their size, shape and the material they are made of. When struck against each other or against another surface, rocks produce a range of sounds from soft tapping to loud cracking. This phenomenon is often used in musical instruments such as maracas and tambourines. So next time you hear the sound of rocks, take a moment to appreciate the unique music they create!
