The beautiful patterns on rice paper are not drawn, but how are they made? Here is a method of making a watermark.

Ink diffusion

Pour half a basin of water into the washbasin and gently touch the water surface with chopsticks dipped in ink. You can see that the ink expands into a circle on the water surface.

Scalp friction

Rub a cotton swab on the scalp two or three times. A small amount of oil on the scalp rubbed by cotton swabs will affect the strength of water molecules pulling each other.

Irregular concentric circles

Then touch the center of the ink circle and see what happens. The watermark will present irregular concentric circles.

Print pattern

Cover the calligraphy paper gently on the water, and then pick it up slowly. What patterns are printed on the paper?
