Chocolate may appear to have little in common with     (1)      oil. But production for consumers requires that both substances travel through pipes. And the thicker—that is, the more     (2)    —they are, the more likely they\'ll clog up those pipes. So physicists at Temple University in Philadelphia have devised an unusual solution to avoid that     (3)      situation: apply an electric field.

The process relies on a concept called electrorheology, in which a fluid can     (4)      from a liquid to a JELL-O–like consistency, or the other way around, in an electric field. The field causes particles in the fluid, like paraffin and asphalt particles in crude oil, or cocoa and milk solids in chocolate, to act like tiny bar    (5)    , and line up into chains.

And the team\'s latest finding could be a     (6)      for the production of low-fat chocolate. Because cutting the fat content of chocolate tends to jam the pipes—the  Augustus Gloop effect. [Willy Wonka clip]

But that     (7)      can be cleared by applying an electric field of 1600 volts per centimeter, parallel to the chocolate\'s flow. The effect would allow chocolatiers to cut cocoa butter by 10 to 20 percent and still not     (8)      the pipes. The study appears in the Proceedings of the National Academy of Sciences. [Rongjia Tao et al., Electrorheology leads to healthier and tastier chocolate]

The authors claim the resulting chocolate has a stronger cocoa     (9)    , and tastes quote, "wonderful." And since the study was funded in part by the Mars Chocolate company—and other chocolate makers are interested—the researchers say the tech may be     (10)      within a year. At which point you can judge for yourself whether electric fields really make a better bar. Or if the taste is shocking.
