Making Rochelle Crystals

[VintagePC]

Seems to me if you can get a nice clean crystal, and make good electrical contact to it, there's no reason it shouldn't work.
It will probably involve a 2-stage step, the second to re-grow a single crystal.

This page describes how to use baking soda as an alternative to the dye fixer:

followed by a recrystallization for purity:

One of the pages says they have a saline, cooling taste. Wouldn't eat too many though, Wikipedia says that the salt is used as a laxative :P You'd be better off trying it with sugar if you want something to eat... hehe.
