You know when you go to open your book at the right page (guided by the scrap of paper/antique leather bookmark* you shoved there) and you can't get your finger in between the pages? No? Me neither, but these designers have obviously experienced difficulty in this area...
They've designed the Abracadabra bookmark. It has an air-filled chamber, half of which is flattened by the weight of the book. You squeeze the exposed side to lift the page. Okay then...
