Balloon folders, and balloonists....
Have you ever seen those guys that inflate the long sausage-shaped balloons, and can twist them and fold them to make swords, and hats, and rabbits, and ostriches, etc...I try to do a bit of balloon folding in my A2 class, and at least I can do
And of course you have seen the hot-air balloonists, that fill up a canopy with hot air, such that the hot-air balloon is floated by the denser atmospheric gas.
