Magic Spin Mug. It uses thermal energy for spinning the fan. It mix the beverage without stir stick and cool the too hot drink. It doesn't need any batteries. It's very interesting and great mug, isn't it? The latter half of this video is like a experiment video of thermal energy. It uses temperature difference. If you feel it boring, please skip and watch other videos.
