"Hold the tube in one hand and pull the string in and out with the other hand; the animal then appears to be moving as if it is charging into each other." (Sirindhorn Anthropology Center, author not specified, CC BY 4.0)

Select a bamboo stalk (long internodes, not too thick-walled) about 30 cm long. Cut 4 slots, each about 1 cm wide and about 4 cm long, for inserting the cows. Pierce holes and insert sharpened bamboo pegs crosswise at 2 points, at the head and middle, for tying string and rubber bands. Carve wooden legs to insert at the top on 2 sides so it can stand upright without rolling over.

Cut softwood into blocks about 4 cm wide, 9 cm long, and 7 cm high. Carve them into the shape of a cow. You may use different colored woods to distinguish them. Drill a hole in the front leg of each cow, and fix both cows to the base with wooden dowels.

Cut a rope three times the length of the bamboo tube, thread it around the pivot point and loop it back to tie to one ox. Pass the other end through to tie to the wooden peg of the other ox. Insert a rubber band at another pivot point so the oxen can move.

Hold the cylinder, and pull the string in and out with the other hand. The two cows will charge toward each other and clash.

Carving a wooden ox figure requires skill, and the tools must be sharp. Currently, only 1 person who makes this toy for the museum to play with remains, age 85. Be careful with knives and saws.
