Solar powered toothbrushes.
This is no ordinary toothbrush, it’s a solar one. But not the kind that you think it is. This toothbrush uses solar rays to catalyze a powerful chemical reaction that completely destroys bacterial cells. And the most interesting part about it is that no toothpaste is required.
Of course, like all cool gadgets, this toothbrush is manufactured by a Japanese company – Shiken.
