[time-nuts] Tongue Testing battery charge levels....

As a teenager I had some experience with tongues and electricity. One was actually lips I'd demonstrate the slight tingle from a 1.5V AA cell between the lips, then hand my victim a similar sized 22.5V photoflash battery!
On an other occasion I tried to strip a length of bell wire / zip-cord with my teeth. Unknown to me my brother had plugged the other end into the mains (UK 240V AC) when I wasn't in the room. Neither resulted in permanent damage but I couldn't taste a thing for about a week.

Please be careful out there!

Hello, TimeNutters--

I have used the "tip-of-the-tongue" test for determining
the state of charge of batteries for many years when
my bench meters are elsewhere.  The strength of the
bitter taste is proportional to the voltage and I have gotten
pretty good at estimating the charge condition of the
ubiquitus little 9 volt batteries as well as a few others
to within +/-  one volt or two.  I recommend not using
this procedure for anything over a 12 volt battery as
above that level the bitter taste turns into an unpleasant
