Puzzling Chocolate

An impossible puzzle that gives the impression of magic. You show a bar of Mini Chocolates with 70 pieces of chocolate. You remove one piece leaving 69. You then rearrange the pieces so it looks like you still have 70 pieces left - an impossibility. But that is not all. You repeat the sequence two more times so a total of three pieces are removed and left in plain sight yet the chocolate bar is still complete with 70 countable pieces! There is even a plastic frame included which fits snugly around the 70-piece puzzle both before and after the three pieces are removed. This was designed by Albert Liao, Neo Chang and Wen Huang to be done with a plastic chocolate bar. Excellent condition. Based on the Freer Tile puzzle.
