Came across this strange thing the other day! How to 'lock' 2 books together!!!!
Simply place 2 books edge to edge, pick them up from these 2 edges leaving the spines on a surface and shuffle the pages together (like clever card players do) so they are overlapped and well shuffled. Now try and pull them apart. You can't? Well that's because the grooves on the paper and the friction of the shuffling action have caused the paper fibres to 'lock' together!
To unlock you have to manually separate each section of pages - DO NOT PULL!!! 1) you will probably rip pages out and b) you might give yourself a hernia!
