The riddle of 3 batteries

You have 3 9-volt NiCad batteries of known and uniform capacity you want to
fully discharge, but you have no wires or other equipment, so the only way you
can discharge them is by snapping two of them together, forming a short circuit
of 18 volts. But you don't want to reverse charge any of the batteries. How can
this be done?

Put all three in a crusher and push the big green START button. When done, you
will have three very discharged batteries, and absolutely no reverse charge.

Hold them securely against the genitalia.

First get some Glycerin, then some Nitric Acid; play with mixing them;
you might get a big *BANG* out of the experiment!

Please, this is such an easy question, can't you just come up with the straight
answer??

And so _very_ important...

Short each on the metal casing of the other, although I prefer my crusher
solution.

well, good one, but still need to sand the batteries to get the metal casings
.... there's also a solution that only involves snapping the batteries together.

I said NO OTHER EQUIPMENT!!!

Make a hollow in the ground with your hands, place batteries in and
wait for rain. Or does a habitable planet count as equipment?

Simply wait and let them self-discharge. The negative post on a
9-volt is wider than the gap between the pos and neg. You could also
use just the neg post from one battery to short the pos and neg of
another. Of course a dead short could damage the battery


Why do you keep posting asinine questions to this newgroup? Is
business that slow or are that bored that you like trying to stir up
debates over stupid things? For your own sake, please get a life.
