Example Sentences

Pitcher rims are notoriously slick—many comprise a layer of wax crystals resembling “the slippery coating of a Teflon plan,” while others have “wettable” surfaces that cause insects to slide straight into the pitcher cup, similar to how cars skid across a wet road, says Ulrike Bauer, a researcher at the University of Exeter in England, who studies the mechanics of plant movement.

From National Geographic

From Science Magazine
