Shake Brush / Toothbrush

A tooth brush has more bacteria than we think. Even you may brush your teeth that have same germs in your shoes. The most cleanable method is sterilizing tooth brush everyday, but many people don't do that because it is too complicate. For this reason, most people brush is exposed to the bacteria. I designed tooth brush that sterilize by itself with using ultraviolet rays lamp. It works when we brush our teeth up and down, then turn into electricity energy and supply electricity power to make clean tooth brush.
