These classic toys are so fun! A Bull Roarer "is one of the world's oldest traditional folk instruments". It makes a very unique sound amongst the musical instruments of the world - the roar of an angry bull! The instrument is made of a 10"x 2" flat piece of wood, attached to a short wooden dowel handle by way of a long cord. Simply swing the bull roarer above your head or in front of you in a circular motion to produce the sound. And you thought you couldn't play an instrument! Made in the USA.
