This drum will  produce resonant, bongy sounds that vibrate up and through a child's body. 

A note about why drums are so very important on your playground:

Research indicates that drumming induces relaxation by enhancing theta-wave production and brain-wave synchronization. Drumming produces pleasurable experiences, enhanced awareness of preconscious dynamics, release of emotional trauma, and reintegration of self. Drumming alleviates self-centeredness, isolation, and alienation, creating a sense of connectedness with self and others.
