Craig Ramsell is the inventor of a percussion instrument called the Boomwhacker. Boomwhackers have a very unique sound, and professional percussionists have actually used them in performance. Boomwhackers form a 2-octave range. They are brightly-colored plastic tubes tuned to the length of musical notes. Portable, durable, easy and fun to play, they range from 12 inches to 24 tall. They can be played solo or with groups. There are a variety of sets to choose from.
