The claims above about DHMO are all true. If you’ve never heard of DHMO (molecular formula H2O), you might know it by one of it’s other names: hydrogen hydroxide, hydronium hydroxide, hydric acid or, most commonly, water. Yep, water.

It just goes to show you can not take everything you see at face value. Sometimes you need to read between the lines and understand the deeper questions of the motives behind the message.
