A drop of water in the desert can be life-saving dew. But what if there are no water and we can’t find water sources for a while？With this bottle, you can get water anywhere. We design the Desert Spring Cup to absorb the water in the sand and then store in the cup. We apply a new material- polymer-coated cotton- to the Desert Spring Cup, which has a strong ability of absorbing water and releases water when changing the temperature.
