Sundew plants are carnivorous, consuming insects by capturing them with small adhesive balls on the ends of their tentacles. The sundew’s adhesive has remarkable elasticity, stretching to 1 million times its normal size (most rubber bands can only stretch to six times their original size). Such elasticity would make the adhesive dew secreted from the plant an effective choice for coating replacement body parts, regenerating dying tissues, healing wounds and improving synthetic adhesives. It is also economical—it’s so sticky and elastic that less than a microliter (smaller than the period at the end of a sentence) would cover 25 millimeters squared (or the size of George Washington’s face on a dollar bill).
