👉 A bandbox, also known as a "bouncing ball" or "bounce box", is an object that can bounce. It is typically made of a material like foam, plastic, rubber, or metal and has a shape with holes in it for air to escape. When the ball hits another stationary object, it will bounce back up into the air. This property of bouncing allows bandboxes to be used as a means of communication between people who are separated by physical barriers such as walls or fences
