Popgun — a bamboo tube with a 1 cm bore, 20 cm long. The plunger rod is 2 cm shorter. Tie the cork with string. The bent handle is 5 cm. Air compression pushes the cork out with a pop.

With the other hand, pull the central rod of the gun toward the body, then push it forward to compress the air inside the barrel so that the cork at the end of the barrel is pushed out with a popping sound. (Sirindhorn Anthropology Center, author not specified, CC BY 4.0)

Select bamboo with a hole about 1 cm wide, such as fairly mature bong bamboo (ไผ่บง). Singe it over a fire to drive out the starch, then cut it into lengths of about 20 cm to make the gun barrel.

Select a round bamboo rod for the central rod, about 2 cm shorter than the tube. Select a cork stopper that fits the tube snugly, and tie it to the central rod with string.

Shave a bamboo stick into a handle about 5 cm long, use heat to bend it to fit the hand snugly, attach the tube that holds the rod and stopper to the handle with glue, then sand it smooth for a nice finish.

Hold the handle with one hand, pull the center rod toward you with the other hand, then push it forward to compress the air in the barrel so that the stopper at the end of the barrel pops out with a "pok" sound.

The bamboo popgun (puen chuk kok) is made from bamboo, a material readily available locally. Take care with fire when heating and bending the bamboo.
