Compass In A Watch


after Martin Gardner

Home / Puzzle Playground / Toys /

Do you know that you can use your analog watch as a compass on a sunny day? Look at your watch and point the hour-hand in the direction of the sun, as it is shown in the illustration. Imagine a line which runs from the center of the watch through a point half-way between the hour-hand and number 12. This line will point south.

The method works for the northern hemisphere. Will it work for the southern hemisphere as well?
