Then I found out, post exposure, that this plastic bag if I put it into a filthy puddle or a stream filled with coliforms and all sorts of disgusting stuff, that that filthy water will migrate through the wall of the bag by osmosis and end up inside it as pure, potable drinking water.
Men så opdagede jeg, efter at have set den, at hvis man lægger denne plastikpose ned i en beskidt vandpyt eller en å fyldt med colibakterier og alle mulige andre ulækre ting, at dette beskidte vand vil gennemtrænge den ellers tætte pose gennem osmose og ende med at befinde sig inde i posen som rent drikkevand.
