What is the most non-aerodynamic material u can think of, and it is easily obtained in about any store?
Answer:
You question is far too vague. It could be a brick for one application, it could be a parachute for another. What is it that you want to accomplish exactly?
[REPOST] Okay, if you are asking what is used for hang glider wings, I believe it is ripstop nylon. You can find versions of it at a fabric store. If you need something more suited to smaller scales, look for monocote at a hobby store. It is used to cover model airplanes, is very light, and sticks to itself when heated for a clean seal of edges.
Next time, if you want say, a suggestion for the covering of a kite, simply ask "What is a good material for covering a kite?" It's pretty confusing if you don't simply ask directly your question - in fact, I'm still not sure if I am giving you the info you are looking for. As mentioned below, something non-aerodynamic has to do more with shape than material - something aerodynamic has relatively low drag/air resistance.

A brick.
Those big blacksmith's irons in the cartoons that always fall on people's heads.
Yeah, anvil. lol!
I like floodtl's answer, I think he means an Anvil.
aerodynamic materials allow smooth flow of air over them, the smoother the material the better the airflow, for a non-aerodynamic material you would want the roughest possible material, choosing what is roughest is based on application, breeze block is fairly rough but not necesarily ideal for your design. velcro is perhaps the least aerodynamic surface i can think of, that is fairly easily available but maybe expensive if you need large quantities.
sandpaper.
its cheap and very ruff/non-aerodynamic when applied to surfaces. but overall i would say a sheet of ply-wood. just try to run with one of those on a windy day.
The shape of an object often has far more to do with its aerodynamic properties than does the actual material. I assume you are talking about creating the largest possible aerodynamic drag possible. As for many things, your particular application may determine which material is best. A 'rough' material sometimes creates more drag, but in other circumstances a 'rough' material actually produces less drag, one common example is a golf ball (see the second link in sources).
Material?
Try making a wing surface out out any liquid. Water is cheap, mercury heavy. Have fun
definitely sandpaper, the rougher the better.
