What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Fits one hand and a child's grip. Small size means a short, tight rumble rather than a long rolling one.
Detail 02
The spring is the sound source. Tilt and shake speed control the rumble; a sharp flick gives a crack.
Detail 03
The head amplifies the spring. Muting it against your body or a hand shortens the decay.
Detail 04
Cosmetic only. Easy for kids to spot in a bin of look-alike shakers.
Detail 05
Cheap enough to buy several for a class set rather than passing one around.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
A spring hangs from a drumhead on the end of the tube. Shaking or tilting sets the spring vibrating, and the head amplifies it into a rumble.
It's a common classroom instrument and needs only a shake to work. The exposed spring is the part to supervise, since it can be pulled or bent.
Yes. Gentle tilting gives a low rumble; a fast shake or flick gives a sharp crack. Holding the head against your palm damps it.
7 inches long by 2 inches across — a one-hand instrument.
