Cleaning out my garage, I found an emergency kit that is used typically for earthquake preparedness. I know where I was working when I was given this kit: it was 2005. So the kit is about 18 years old.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In that kit were the usual things: emergency food rations, mylar blanket, bandages, Tylenol, flashlight, that kinda stuff and also a pair of liter bottles of water. I noticed that both bottles had compressed, which was odd considering the seal was intact and both still held pressure (they can’t be squeezed.)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>There was clearly quite a bit of water missing from both bottles, but no way out for the water that I can see. So… I weighed them on a postal scale. It freaked my beak: both bottles weigh in at 816 grams.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Conclusion: both bottles lost about 20% of their volume from a sealed disposable plastic bottle over the course of 18 years, without harming the seal. They lost the same amount down to the gram.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any explanations please?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>spike<o:p></o:p></p></div></body></html>
