Thanks Paul and Pam!
I think I said this part wrong - I do indeed allow the MMS1 to develop into chlorine dioxide prior to using an eyedropper to put it into the capsules. I use the 50% citric acid to avoid having to fill a bazillion capsules ;O) One 3 drop dose (3:3), allowed to sit for at least 30 seconds, then into the capsule it goes.
I could probably fit a 4 drop dose into one capsule, but after the mixture has done its thing and chlorine dioxide has formed, I fill the balance of the capsule with a drop of plain water if there is a gap. Works like a charm every time.
Anyways - this was so easy that it got me to wondering about the possibility of premixing the MMS2, allowing it to develop (no clue how long that takes - I was under the impression it is instantaneous), then eye-droppering (is that a word? probably not!) it into capsules in the same manner.
Anyways, good point about it exploding, Pam. Capsule bombs is not the goal
