i got a few quartions regarding to potassium permangate ( KMnO4, cindy's cristals or whatever ).<br>were do you buy a small quatity of that stuff ( don't wanna buy one of those HUGE packs from some gardening/fish shops ) ( for a psk ) ? and if you repack it, what type of container should you use ( its very oxdizing ) ? <br>and the most importent quation is:<br>Is worth buying it / putting it in a psk ? i mean it usefull as <br>-antiseptic <br>-waterpurifciation<br>-snowmarker<br>-artifisial flint ( mixed with sugar )<br>-chemical fire ( mixed with glycerin )<br><br>but it is also <br>-lethal in large quatity ( swallowed )<br>-can cause burns on the skin wenn it is repeatedly used as an antiseptic ( or exidental spill on the skin of an large quantity )<br>-can cause instand blindness wenn in contact with your eye's<br>-hard to dose. i mean, how do you get 2-3 crystals ( dose for waterpurfication ) out of a vial ? with out poring some in your hand first ( causes irtation, possible burns, etc. ) even using tweezers to get only 2-3 crystals is like impossible.<br>-very hard to optain<br><br>so is it worth the risk ?<br>
