'Coolrunnings' by Jaehwa Lee is a device that cools water to offer a fresh, crisp drink.
There's nothing worse than downing warm water on a scorching hot day but there's no need for that with Coolrunnings. It's a concept design meant to instantly turn lukewarm water to a refreshing cool temperature that will satisfy the sandstorm stirring up in the throat.
The slender turbine works by being placed over any rubberized cap bottle. Users will have to twist the device, turn it on, and give it a good shake. The cooling process works because there's a cooling pin equipped under the bottle cap and the shaking accelerates convection. To maintain its power, Coolrunnings is powered by a USB charge to offer users instant cold water every time. Coolrunnings by Jaewa Lee is an innovative concept design that works towards eradicating the use of plastic bottles.
