Demon Snapper in original box

The snapper has rightly been a popular novelty for decades. You demonstrate that, when you pull the plunger out of the tube, it snaps back as though attached to a rubber band. Hand it to somebody else and they will fail to get the plunger to snap back. However, as soon as you take it back you can repeat the effect. This snapper from Davenports is made from quality plastic and is particularly smart. Complete with original instructions.
