The Invisible HelmetThis is a bicycle helmet that the rider inflates when it is needed. When it isn’t in use it fits like a hood around your neck. That’s the reason it is invisible. It not only solves the problem of what to do with the helmet when it isn’t being used, it is also rather fashionable. But as any fashionable thing, it looks stupid.
