Wooden Mental Logs by TCC MagicIn the first phase, the performer asks the participant to shuffle the logs randomly and form four rows of four digit numbers. In a split second, the performer calculates the sum of these numbers, which, when verified with a calculator, proves to be accurate. Transitioning to the second phase, the participant shuffles the logs once more, freely moving each wooden log up or down. This creates a layout where numbers of various digits are added together.
