内容简介：
What can travel through cement walls, fly into your nose, and grow from a tiny dot into a mass that spreads across acres? Whatever it is, time is short. Some rules seem awfully fussy: don't run with scissors, tuck your leggings into your boots. But what about one like remove infected stones? Or burn moldy clothes? On this day, crazy rules become more sensible to Jacquie Metrico. They were the key to keeping her friends alive. Join Jacquie and Jeff in the second story of the Metrico Mesh series, discovering absurd logic and scientific oddities in the world around us.
