Science behind the experiment:
Sound travels through the air as vibrations. As your fingers slide down the string, vibrations occur. The vibrations travel around the cup, which amplifies the sound producing an eerie scream. Aaaah! Try different sizes and different cup shapes to see how this affects the sound.
