Have you ever noticed that every single time you cut into your morning grapefruit, you've got to dodge or else get a spritz of acid in the eye? So did this team of mechanical engineers, and they realized they could put that phenomenon to good use. Every orange is pocked with oil-filled glands that explosively rupture when the peel is broken, and the experimenters used engineering tools to measure exactly what the pressure states caused those glands to shoot their substance in a high-speed jet. Their findings, which were presented at the annual meeting of the Society for Integrative and Comparative Biology, could inspire a new type of one-use asthma inhaler.
