¿Eres un aventurero que pasa la mayor parte del tiempo al aire libre? Aquí tienes algo genial de The North Face: la Luceta Húmeda. Básicamente es una hoja de papel que puedes doblar y usar agua para iluminar científicamente y usar por la noche durante tus excursiones de campamento.

With travelers in mind, The North Face's Water Lamp is thin enough to slide into any backpack or travel bag since it is essentially just a sheet of paper. To use, it has an instruction to fold the paper in certain ways and make it stand like a lamp, use water on a specific spot, and it will begin lighting up so you can use it to light a spot while on the great outdoors.

As mentioned in the instructions, the paper illuminates because of the application of water as it "allows electrons to flow from the zinc to the copper in the paper. This electrical current powers the lamp."
Indeed, it is a handy tool to have around since not only does it provide light, but it is also eco-friendly as it doesn't require any electricity to operate.
Therese "Gang" Badoy Capati, who posted it on her Twitter account (@gangbadoy), mentions that it is currently available at The North Face in Shangri-La Mall, Manila. We've contacted the company and inquired of its price.

Is it the same as the digital clock that also works with water?
