watso was flicking through the channels last night, and chanced upon a segment, where they were "cooking dry urine" - ie getting rid of all the water - and then making toothpaste.
maybe a long time ago, toothpaste was a mixture of some oil (forget which one - but probably some plant extract), cuttlefish shell and dried out urine ... the tooth brush was made from donkey hair.
watso the rtc hunter gave about a fraction of a second to the good old days, then opted for toothpaste from the reject shop for $1 per tube.
mmmm watso used to have a brother in law, who was a dentist, and his family used the cheap "black and gold" toothpaste - because it was "all the same"
