Lin Mangkon (Thai Paper Blowout, "Dragon's Tongue") — a 20-22 cm Card Cone and a 10 × 20 cm Kite-Paper Tube on a Spring Wire, Rolled up, Unfurling when Blown, with Dyed Feathers at the Tip

Roll card into a cone about 20-22 cm long, about 3 cm across at the mouth and 0.5 cm at the narrow end.

Cut kite paper 10 cm wide and 20 cm long. Fold it lengthwise, overlap the edges and glue them to make a long tube, and press it flat. Lay a trembler wire as long as the tube along its middle and cover it with patterned paper the whole length; let the glue dry. Lay the tube wire-side down, fold one end back over the tube, and insert dyed chicken feathers into the inside corners of that end on both sides. Glue the feathers and the end shut so no air escapes.

Fit the other end of the tube over the mouth of the cone and glue it, then wrap patterned paper round the whole cone. Roll the tube up, wire side inward, down to the cone.

Blow into the narrow end of the cone: the kite-paper tube fills and unrolls. Stop blowing and it rolls back on the wire's spring.

The lin mangkon is a Thai folk toy made of paper. Beware of the sharp wire ends.

The trembler wire is linked to general craft wire, and there is no listing for kite paper, so it is named in the text.
