An anonymous reader writes "Scientists have developed a porous chip that can identify liquids instantaneously. Each liquid's distinct surface tension determines how much it seeps into the pores of the chip, which the chip uses to tell liquids apart. The researchers also decorated the chip with a secret message (ie, brand name) that only shows up when certain liquids are applied. The chip is so sensitive it can distinguish gasolines with varying proportions of ethanol, and could help clean-up crews identify spills in the field."
