Although much is understood about the mechanical behaviour of macroscopic machinery, less is known about their molecular equivalents. It is now shown that for molecular machinery consisting of hydrogen-bonded components their relative motion is strongly accelerated by adding small amounts of ‘lubricating’ water, whereas other protic liquids have much weaker or opposite effects.
