balsa

Balsa is a light wood.

The children were asked to model an airplane out of balsa-wood.

In May of 1953, the balsa wood strips were again removed, and the X-4's dynamic stability was studied in the original flap/speed brake and elevon configuration.

The thickened flap/speed brake tests had been encouraging, so balsa wood strips were reinstalled on both the flap/speed brake and the elevons.

As the balsa has slippery hairs on its leaves, the vine can't get a hold.

In 1947 the Norwegian explorer Thor Heyerdahl set sail from Peru on a balsa wood raft called Kon-Tiki.

That first meant replacing its hinge pins with ones made out of balsa wood.

Objects that are less dense than water, such as balsa wood, icebergs, and inflatable rafts always float.

In 1947, the Norwegian explorer Thor Heyerdahl and his crew constructed the Kon-Tiki raft out of bamboo and balsa wood.
