Boomwhacking

Boomwhackers evolved at a time when junk bands and performers using instruments made from recycled materials were very popular. A boomwhacker is a lightweight, hollow plastic tube, tuned to a musical pitch by length. Hollow plastic tubes are hit against your hand to create a musical sound. Different
colour Boomwhackers each have a unique sound and creates instant musical tunes
when used together. Ideally suited to audience participation and may be used in
large number of participants.
