Make your own toothbrush.
- Boil a handful licorice sticks (medium thickness - 5 mm is about right, 3 mm too thin, 7 mm too thick) with 3-4 cinnamon sticks and about 10 cloves. If you like you can add ginger, as well.
- Let simmer until the sticks are soft. This takes about 4-5 hours.
- Strain out the licorice sticks and put them into a longish container.
- Cover with vodka, close lid on that longish container.
- Let sit overnight.
- Put sticks into dehydrator, let dry on full heat (about 60 deg. C) until dry.
Using these toothbrushes: chew open 1-2 cm of one end, use that to brush with. You can't reach around corners. When the chewed-up bit is all untidy, remove the untidiness with scissors or a knife and chew up the next bit.
You're guaranteed to get interesting looks when you use this.
I got the recipe long ago from one or the other book by David Hoffman. I think (but I'm not sure) he recommends also trying birch twigs. If you want to boil birch twigs until soft you'll need to wait for a long time. Also, after boiling them for 4-5 hours you have birch twigs, not tooth brushes. They simply don't open up when chewed. I've tried it, it doesn't work.
