A Deception

You turn the cap counter-clockwise because the bottle rotates to the right;

This makes sense until it is realized that counter-clockwise is to the left;

But does this solve the problem?

Clearly, the motion of the bottlecap and the motion of the bottle must be in opposite directions; But they're not; Perhaps we are being deceived;

The only solution is that the bottlecap is in fact moving to the right, as per the horizontal not top view, and hence the bottle is moving to the left, contrary to intuition;

Why would the bottle move to the left?;

Evidently because someone thought that counter-clockwise was intuitive;

But at this point, it seems like they're being deceived;

Back to the beginning::
