How can we make a wind speed measuring device?

Our anemometer was made from four cups fixed to a wooden cross that could move freely around. The cups were made from the nuts of a calabash tree. The rotating device was connected to a dial that moved with it. The dial rotation was counted using a simple sand clock to get an estimate of relative wind speeds.

Wind vane How do we find out wind direction?

A simple wind vane was constructed to show the direction of the winds. To find north, south, east and west, we used a magnetic compass. Once these directions were known, we attached an arrow to the top of the device and the movement of the pointer gave an indication of wind direction.
