Shave bamboo about 20 cm long until round, one end about 3 mm thick and the other 1.5-2 mm.

Cut coloured paper into a square, for example 10 cm. Cut along the diagonals in from all 4 corners to about 0.5 cm from the centre, giving 4 triangles. Punch a round hole in the centre that fits loosely on the stick, and a hole in one base corner of each triangle.

Put the pinwheel on the handle, and push another piece of drinking straw tightly onto the handle above it.

Hold it and run into the wind, and the pinwheel spins.

The paper pinwheel is a Thai folk toy that supports emotional and social development and an understanding of mechanics. Take care with the knife and scissors.
