Man... I remember as a kid we had salesmen going around "water magnetizer" in our neighborhood, and giving out different types of water for people to taste. A neighbor ended up buying the thing! And it was actually expensive, it wasn't a 10 bucks scam. It required ordering and took a few weeks to arrive. Then I went to check it out and it was just a cover for those commercial watercooler bottles with some magnets. But they swore their water tasted better.
