Very silly, but there's nothing wrong with that! The special glasses have 13cm protruding stem to which the other components can be attached to play all sorts of ridiculous games & activities using only movements of the head. Nose Hoola-Hoop & Basketball require skill & practice, the Ball Bearing puzzle patience & subtlety whilst vigorous head shaking is usually sufficient to operate the Clackers. At least one set should be purchased for any gathering of young or mixed ages; everyone can join in, have a go & look completely ridiculous.
