A flashlight that does not require batteries should pique anyone’s interest; irrespective of whether you are a traveler or not. All you need to do to charge the flashlight is to give it a good shake for around 30 seconds. This is sufficient to keep the flashlight charged for five minutes. In case you’re wondering how this contraption works, it uses the Faraday Principle of Electromagnetic Energy. And yes, the flashlight floats on water, is waterproof, and the beam is visible from a mile away.
