A simple ground level wind direction indicator:
I don't have a good picture so here goes:
a round Rx bottle cap as a base
a "squirt nozzle cap"( pointy one like ketchup or mustard) cut off and glued to the underside of the bottle cap
pipe thread tape (mylar tape) attached to the top of the cap
put it on the top of launch rod, you have ground level wind
