Ask to someone to analyse your 2 bill. Nothing special like ordinary bill. Place one over the other and ask someone to cut right in the middle.(you should take the 2 bill in perfect rectangle position). When you separate the bill you unfold them and surprise the 2 bill are restored !
Step 5: How It Works.
When you place the bill , place it face to face .
when you cut the bill ,the thin layer of rubber cement joint them in the cut .
Try with some paper before you cut all your money . :)
