How to Chew Betel Nut in Papua New Guinea

If you ever go to Papua New Guinea, the first thing you will notice is the brilliant red-stained teeth and lips of the local men and women.

    Move the betel nut wad to the side of your mouth and then bite off the piece of mustard seed that has the lime powder on it. Make sure to not put the lime directly on your mouth or gums as they will feel a burning sensation. Instead try to bite the mustard seed directly into the betel nut wad. As you chew the mixture together, they will form a chemical reaction that will make your teeth and lips red and provide a mild high.
