How long are you going to be gone for? If it's just a couple of weeks, I put some MMS and CA in separate 2 oz HDPE bottles (white) with the words "water purification" written on the side - and put the 2 bottles in my makeup kit along with all my other makeup lotions, etc.. I make extra sure that the tops are on securely and that the makeup kit is waterproof. NOW, I've not done this for a foreign country, only for travel in the US.
Just out of curiosity - do airlines cause problems with taking MMS on the airplane? I guess if you put it in your suitcase - it is fine but just wondering if going through customs/inspections at some of the countries, if they challenge anyone.
We are looking to do some travel next summer so this has been helpful for me. I am just reading the books on MMS and DMSO and I would love to have them as part of our emergency kit. It is really amazing some of the stories in there.
