A boomwhacker is a lightweight, hollow, color-coded, plastic tube, tuned to a musical pitch by length. Boomwhackers are used as musical instruments in the percussion family. Boomwhackers produce musical tones when struck together, on the floor, or against nearly any surface. They can also be grouped together and struck with mallets in different configurations, in specialized holders (homemade or available from the manufacturer), similar to a horizontally-aligned xylophone.
