Soon a sticker on your fruit may tell you that that peach is ready for a juicy bite or that, yes, you have ripe bananas--and it won't be that little old Chiquita sticker telling you so. Within a few years, new RediRipe stickers might start showing up on supermarket fruits, turning blue to indicate ripeness. An Arizona professor invented the stickers to detect levels of ethylene gas given off by peaches, apples, pears, avocados, bananas, as well as other fruits, veggies and flowers when they reach their potential.
Ethylene acts like a hormone in plants, by the way. It makes me wonder if we'll ever get a sticker to light up when our milk, cheese, and ice cream is laced with artifical hormones? That sticker would have to turn from a pure white to a putrid, green-beige pus color. How about a little gold star sticker to light up a shocking chartreuse hue when there's radiation in our backyards? I also wouldn't mind a sticker to glow black to show when we're breathing pesticides outdoors or formaledyde indoors.
