"Moreover, our experiment provides the first evidence that the appreciable and measurable violations of the second law of thermodynamics in small systems occur not only at simulation time scales (femtoseconds), but also at colloidal time and length scales (seconds)."

Analogous long-duration kicks would be observed if the colloidal particles are placed between the plates of a liquid dielectric capacitor (flows in the liquid able to "kick" are clearly seen in the video):

In an electric field, water develops a specific pressure that pushes in all directions and can result in an eternal (limited only by the deterioration of the system) motion, on condition that the system provides suitable channels for water to move through. If, in the simplest case, two opposite charges immersed in water are close enough to attract each other, the specific pressure that develops between them counteracts the force of attraction and the latter apparently decreases:
Wolfgang K. H. Panofsky, Melba Phillips, Classical Electricity and Magnetism, pp.115-116: "Thus the decrease in force that is experienced between two charges when they are immersed in a dielectric liquid can be understood only by considering the effect of the PRESSURE OF THE LIQUID ON THE CHARGES themselves." http://www.amazon.com/Classical-Electricity-Magnetism-Second-Physics/dp/0486439240?tag=viglink21401-20
"However, in experiments in which a capacitor is submerged in a dielectric liquid the force per unit area exerted by one plate on another is observed to decrease... [...] This apparent paradox can be explained by taking into account the DIFFERENCE IN LIQUID PRESSURE in the field filled space between the plates and the field free region outside the capacitor." http://farside.ph.utexas.edu/teaching/jk1/lectures/node46.html
Tai Chow, Introduction to Electromagnetic Theory: A Modern Perspective, p. 267: "The strictly electric forces between charges on the conductors are not influenced by the presence of the dielectric medium. The medium is polarized, however, and the interaction of the electric field with the polarized medium results in an INCREASED FLUID PRESSURE ON THE CONDUCTORS that reduces the net forces acting on them." http://www.amazon.com/Introduction-To-Electromagnetic-Theory-Perspective/dp/0763738271
The specific pressure that develops in water placed in an electric field is NON-CONSERVATIVE. This means that, if suitably harnessed, the pressure will do work AT THE EXPENSE OF AMBIENT HEAT (in violation of the second law of thermodynamics).
