The Resonance Air Column (WA-9606) emits a very loud sound when the plunger is moved to a node position. It works as well as a water column but without the mess. The secret is in the long molded piston head, which is very efficient in reflecting the sound waves. The plunger handle is made of flexible acetyl so it will not break.
