The tube is filled with nothing but quantum sudoku, distilled from the finest papermills in Japan. When squeezed, a material approximately the consistency of toothpaste will emerge with a partially completed Sudoku. Spread over a wide enough area and the entire puzzle will become visible, and the product will instantly harden to allow drawing on it. Pens are not provided.
