Step 11Dry the Crushed Charcoal

Dry the Crushed Charcoal
I spread the crushed charcoal paste on some newspaper and put it in the sun.
It was still wet after a day in the sun so I dumped it onto tinfoil on a pan and put it in the oven.
I tasted a mouthful of charcoal to see if it was any good. It didn't taste like a smoldering fire, which is what I was afraid of. I couldn't figure out what the taste was. Then I realized the taste was the taste of no taste at all. It was absorbing all the stuff from my mouth that could activate a taste bud. This was a non-taste I've probably never experienced before. I remembered how the old nuns in the old-folks convent at home used to eat burned toast for the charcoal. Those nuns were the best educated people in the area for a hundred years or more, so I figured they knew a thing or two. I chewed it up and swallowed that mouthful of tasteless carbon with gusto. I smiled with clean black teeth.

i think there will be a difference. the coal is used as a filter bacause of its big surface, if its wet you will have less filtration. plus when i was in the bundeswehr we were told not to let our filters go wet.
