¿Clap, Clap! is made to open and to close. Because every time you open and you close it, there is something inside that moves and makes a noise:Flap, flap... a butterfly flaps its wings. Fom fim... an accordion stretches and shrinks. Bong, bong... a boy plays a drum with all his energy. Clap, Clap! does not need batteries or battery, just your hands, one on each side.
