You fill up a glass with 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. This gimmick fits any PET plastic bottle. There are two other models, with a slightly different attachment, one for a glass bottle and one for a can.
