You will be instantly engaged when you start turning the lever of the HypnoGizmo. As the barrel turns you will enjoy watching metallic balls rhythmically roll back and forth across the barrel. This is a super fun engaging item for individuals who are highly visual. Its great for road trips or waiting times.
Metallic balls are securely enclosed inside a thick plastic case. Please note the balls do make noise as they roll back and forth.
