Find a mango leaf of a good size, not too young. Tear both ends of the leaf, on opposite sides.

Cut off the protruding stalk to use as the handle, and pierce a hole in the middle of the leaf.

Push the cut stalk through the hole in the leaf, base of the stalk at the front, so the leaf does not slip off while spinning.

Hold the end of the stalk that sticks out behind the leaf, stretch your hand out parallel to the ground and run forward; the faster you run, the harder it spins.

Mango leaves were easy to find in the past, so parents made these pinwheels for children to play with friends; teaching children to make their own fosters imagination. Take care with the knife when cutting the stalk.
