Finding North with just the sun

This method does not require you to know the time of day or have an analog watch. All you need is a shadow being cast by the sun.

Called the Shadow tip method, here it goes:
Find a meter long stick-like object.
Hold it vertical on the ground.
Mark the tip of the shadow of the stick. This point is West.
Wait for about 10-15 mins for the shadow to change a bit.
Now mark the new location of the tip of the shadow. This is East.
You now have the W-E line, so figuring out North is easy. If you stand if the first point to your left, and second to the right, you are facing North.

This makes sense. The sun appears to move from East to West. So, the shadow of an object that remains put, will move in the opposite direction, i.e. West to East. Hence our first point was west and the second, east.

So, the next time anyone asks you which way is North, ask them to come back after 15 minutes!

I checked if using the analog watch and this method, gave the same north and they were pretty damn close!!
