"Toothpaste Dots for camping. Lay out foil sheet or parchment and make rows of dollops of tooth paste. Allow to dry for 2-4 days. Sprinkle baking soda on top to keep from sticking. Repackage in small bags. To use simple pop one dot in your mouth, chew, then add a small amount of water in your mouth and start brushing. This tip reduces weight in your pack. could also work for travel in general."
Interesting thing I found on Pintrest, I wonder if the home made toothpaste in my last post would work this way too?
