How can a water bottle turn air into water? With "imagination," SpongeBob SquarePants might say.
But no, the Fontus Airo water bottle accomplishes the trick with science — the principle of condensation, to be precise.
Humid air enters the top of the water bottle where it's chilled by a solar-powered cooler.
Water droplets form and run through a filter down into the bottle.
Fontus says it can produce about 1.6 pints of water in an hour — about the size of a 27 ounce bottle of Gatorade.
Problem is, it'll only do that in "really good conditions."
Really good conditions: 86 to 104 degrees Fahrenheit with 80- to 90-percent humidity.
And you probably don't want to use it in the city.
It's not designed to filter airborne contaminants.
It's also yet to be launched as a crowdfunding campaign, so it may never see the light of day.
But at least we know it's possible to turn air into water. Remember this billboard from Peru's University of Engineering and Technology?
"The billboard has a unique technology that captures the air humidity and turns it into drinking water," said the narrator in a UTEC video.
The difference is, the billboard's water is filtered for contaminants.
