Why? Because Vancouver water is soft and Montreal water is hard. That makes a big difference when it comes to satisfaction with hair washing. Hard water contains dissolved calcium and magnesium ions which react with soap to form a precipitate. This is the classic “bathtub ring.” The grayish deposit is bad enough on a tub, but you sure don’t want it on the hair. Vancouver has very soft water and soap will suds nicely and will not leave a deposit.</p> Fri, 02 Jul 2021 21:03:43 +0000 Joe Schwarcz PhD 8775 at /oss /oss/article/environment-health-news/moldyuuck <p>Molds can sometimes grow to an impressive size. A story has been making the rounds in Montreal about a large piece of mold being found in a sample of Oasis juice. You would think from the press coverage that such a thing has never been seen before. Another sample was found last March in a carton of Minute Maid orange juice in Britain. In that case a little girl got sick from drinking the juice. In Montreal it was just yuuuck.</p> Thu, 23 Jan 2014 03:32:00 +0000 Joe Schwarcz PhD 2076 at /oss
