And who invented the Wind Sock ?
And where was it first used?
If we define a windsock as something like:
a conical fabric tube open at both ends used for assessing wind velocity for a practical purpose
then its use is probably as old as bows and arrows. I've certainly seen ancient oriental prints of chinese armies with recognisable windsocks being used by hordes of archers, presumably to judge how much to "lay off for drift".
So suggested answers are:
Who - the Chinese
Where - er ....China?
