11/3 Physics/Chem question: when I microwave water for tea (usually
it gets to a superheated state w/o boiling over) I can often see
an oily layer at the top. Anybody know what causes this? oktnx
\_ film from soap or something left in the cup/glass?
\_ You're drinking city water.
\_ moron, you can't superheat water without pressurize it
\_ wrong.
\_ it's just the oils within the tea.
\_ It's filtered tap water (no tea yet) and I never see it
except when the water is very hot and not boiling.
\_ Are you interested in BS speculative answers?
\_ Definitely. It's a slow day.
\_ Well, then, maybe it's not oil at all but
a thin layer of very hot water.
Alternately, maybe it IS oil, but it was oil
that was sort of embedded in your teacup, and
didn't float to the top until things got very hot.
To test that, put tap water in, heat, pour out
\_ Try it with distilled water
hot water + oil, put more water in, heat,
and see if the oil eventually runs out.
\_ I already told you: you're drinking shitty city water.
\_ Try it with distilled water vs. tap water. Also try cup vs
sterilized microwave-safe glassware. Basically, use all of that
science training they tried to beat into you.
\_ Clean your damned turdcovered microwave.
\_ yeah i am guessing the oil spatter in your \uwave floats around
when you are nuking or there is oil floating around your kitchen
which lands in the mug. kitch != fab lab. --psb
\_ Speak for your own kitchen. *Mine* is cleaner than the
best fabs IBM has.
\_ dude, you are SO gay. admit it to yourself.
\_ I'll let you know as soon as your cock ring stops
bouncing off my teeth, loverboy.
\_ Dude it's rat pee. From rats stuck in the sewage system, which
is where your "drinking" water comes from anyway. You think they
filter it? Ha ha, you fool. They just send it through the giant
underground CIA rat pee farms and add some fluorine. -John |
