Kai Krapong (Thai Cup Chicken, Kai Kratak) — a Cup Pierced at the Bottom, a String Tied to a Stick or Clip; Stroke the String with a Damp Cloth and it Clucks like a Hen

"Take a cloth, tissue or sponge dipped in water and wrung out until damp, or just your fingers, grip the string and draw downward, and it makes a long 'pok' sound." (Sirindhorn Anthropology Centre, author ยุวดี ศรีห้วยยอด (Yuwadi Srihuaiyot), CC BY 4.0)

Use a paper or plastic cup; if you use a condensed-milk can, open it and remove every sharp edge. Pierce a small hole in the bottom.

Tie one end of a jute, kite or cotton string to a scrap of wood or a paper clip. Thread the other end into the hole from the top of the cup through to the outside, and pull it until the wood or clip stops at the hole.

Decorate the cup as a chicken as you like.

Grip the string with a damp cloth, tissue or sponge, or your fingers, and draw it downward for a long "pok". Try other kinds of string, other cup sizes or other rubbing materials, and notice whether the sound gets louder or softer.

Khun Thongchai Khusuwan of Lampang, demonstrating it for the Ban Phiphitthaphan museum, said it makes only the hen's call when she is about to lay: one long pok, then five or six short ones. If you use a can, remove every sharp edge.
