This is a special activity that only happened with the elder Balinese in the past. They are hitting their tobacco with a special tool, before they going to chew it. Mako or Tobacco believed to be a technique to strenghten the teeth, althought it will make the bright yellow to the teeth and mouth. This activity called as "Numbuk Mako", likely will be a gone culture after all Balinese now start to do teethbrushing.
