A lot of new ideas in the adhesive industry are provided by the nature. Recently, sicentists are studying the substance making chameleon tongues sticky, and the research results may bring new invention in adhesives technologies. Scientists compared the eating habits of chameleon with those of a human eating a giant 25 pound hamburger using only the tongue to get it into their mouth. But why the tongue of chameleon is so sticky? The reason is that a special and sticky mucus coats the tip of its tongue. To test its adhesive properties, scientists coated a glass plate with chameleon tongue mucus and rolled a steel ball down the glass plate to see how much the natural glue would slow it down. Interestingly, when the ball was moving very fast, the mucus presented its strongest adhesion. Since that’s how chameleon tongues move, the strange phenomenon makes absolute sense. Though the scientists couldn’t guess at how this discovery will be used by humans, they correctly assumed that the adhesives industry would be the most likely to find an engineering use for sticky-at-speed glues.
