Remember when you were a kid and you had a spy kit that had a secret covert message written in it, and the only way to decipher the message was by using a special colored lens?
Now you can have that same fun in the form of a clock. The hour and minute hands both have colored lenses on them to show the hidden, filtered numbers.
~ The minute hand has a green lens which displays the numbers in minute form (by 5's).
~ The hour hand has a red lens which displays the numbers in hour form (1-12).
Size: 16 in. (Large Clock; the size of a large pizza)
Power: 1 x AA battery (not included).
Materials: Aluminium and glass.
