You fill up a glass with beer or a soft drink from a bottle. You adjust your tie in a slightly absentminded way and do not realise that the glass remains suspended in mid air while you do it. The glass is suspended in mid air! You grasp the glass, as if nothing has happened, continue pouring and eventually enjoy your drink. Nice glass in unbreakable plastic. There are two models, with a slightly different attachment, one for a bottle and one for a can.
