Heinz --
I must have hit save, not send on this message earlier this week. Sorry to
not notice.
I'm no chemist, but in my Mr. Wizard science experiment, I used a clean
glass pint jar (it was a canning jar) that was about 3/4 of the way full.
It bubbled. A lot. Not a rolling boil like you were making soup, but enough
that there was no question in my mind that I had severe moisture
contamination. I'm just curious if you see the same thing. I may just be
un-lucky.
I used a hot plate out in the garage. Had the same problem when I was headed
to the kitchen. BTW: I sneaked the candy thermometer out under my shirt.
I replaced the fluid with regular old everyday DOT 3 fluid. I got a gallon
from a local auto parts house.
