Looks more like a huka to me!
" To make a pooter:
· Get a small, clear jar with lid, 2 fat flexible straws, some plasticine, a small piece of nylon stocking, and some tape.
· With a nail and hammer, punch 2 holes in the lid large enough for the straws to fit into.
· Stick the straws into the lid and seal the spaces around them with plasticine. For your mouthpiece, cut the outside end of one straw down to about 6 cm (2 3/8 inches); tape the nylon piece over the other end of the straw. Screw the lid firmly onto the jar.
· To collect an insect, hold the long straw over it while you suck gently through the other straw. The insect will be drawn into the jar. "
