Electricity produced from water may not require quantum mechanics, but it is quite interesting. This water-powered alarm clock generates electricity using water; in fact, any other electrolyte liquid can also be used, such as soda, coffee, or even beer. You just need to add the liquid into the tank on the back of the alarm clock and it will immediately display the time and date clearly. Even after using it for several weeks, the water level barely drops, even if we don't add more water. How does it work? Isn't it magical? Its internal converter can extract free electrons from water molecules and produce a steady current to power the alarm clock. Interestingly, you can also insert flowers into the tank on the back of the water-powered alarm clock, turning it into a vase. Currently, this product is priced at $13 abroad.
