Can you buy a propeller caps from city beach?

I'm not to sure but i think Propeller caps are silly, because the propeller needs a engine, and clearly the human body is not an engine, for this man-made propeller, unless they attach some mouse running wheel thing to it and some how crazily allow that wheel to send that propeller hat into a fast enough motion to fly. But either way how do you control the propeller hat? there is no steering mechanism. So this question is Not answerable and therefore should be destroyed.

No seriously the answer is YES. The site does have it. I'm not too sure about in-store, but you might as well buy it online... It's only $12 and free express shipping.

Ebay will also sell it.
