I had forgotten to warn people about DHMO. Good thing you brought it up, that could have been a serious oversight. The safest way to prevent ingesting DHMO is to boil your water for at least 30 minutes per pint of water to make sure all the DHMO evaporates before drinking. Then you'll be left with DHMO-free water. <img src="/images/graemlins/laugh.gif" alt="" />
