Materials: Wood and Paper Dimensions: 75 x 85 x 20 mm How it works: Put the sundial on an horizontal plane and direct it southwards in such a way that the tip of the compass meets the signaled and coloured N on the windrose. In this positition we will see that the string casts its shadow over the two sundial quadrants showing the real solar time.
