Anemometer (was $14.95)

WAS $14.95 now reduced to $9.95 while supplies last!

This colorful working model is sensitive to breezes as slight as 2 mph. Since it rotates at speeds 1/6 that of the wind velocity, wind speeds can be determined quantitatively by counting the rotations.

Includes four plastic molded cups, 3 black, 1 red for contrast; low friction axle; sturdy plastic base; instructions with sample problem and wind speed chart.
