This wave or ocean drum from Percussion Plus is a wonderfully simple instrument. It has a red wooden rim and two taut clear plastic skins which house ball bearings inside the drum. When the ocean drum is moved from side to side the ball bearings move over the plastic hitting each other to create an amazingly realistic sound of the sea.
The drum's sturdy construction means that it is able to withstand use in the classroom. A great addition to any percussion pack for seaside sound effects.
