t’s no secret that unwanted chemicals lurk in our food and drinks. But what if a little pill could warn us before we gulp down pesticide-laced water?
Researchers have been experimenting with an unlikely drugstore buy: dissolvable minty breath strips. A team from McMaster University in Canada discovered that pullulan, the same slimy fungus used to make the breath freshener strips, could also be used to make pills that contain pesticide-detecting enzymes. Just drop the pill in a glass of water, let it dissolve, and watch for any color changes.
