        A Faster Way to Test Codes

        In this Cyberchase clip, Matt shows Jackie and Digit how to make a decoder. He writes the alphabet on the top half of his yo-yo and the numbers one through twenty-six on the bottom half. He explains that by lining up the letter "A" with different numbers, they will be able to interpret different codes. Jackie tells him to line A up with 3 and decode a series of numbers. After writing down the corresponding letters, Jackie reads the secret message, "Grab it now, The Hacker," to the team.
