A Boomwhacker is a percussion instrument in the plosive aerophone and idiophone family. They are lightweight, hollow, color-coded, plastic tubes, tuned to a musical pitch by length. They were first produced by Craig Ramsell through his company Whacky Music in 1995. The term is now a registered trademark by Rhythm Band Instruments.
