Sundial

The contestant was presented with a number of circular pieces to be fitted together into a cylindrical shape. The two sides of each piece were coloured red, green or blue, with two red sides fitting together, two blue and so forth. The top piece had a sundial mounted upon it. When this final piece was placed, a spotlight would shine revealing the time. The contestant would then set the giant clock on the wall to this time, and the crystal would be released.
