Dew Bottle / Survival product

There is a huge temperature difference between day and night. ‘Dew Bottle’ creates water in the way of principle of making dew.the product stores solar heat inside the product itself, and when the temperature goes low, it creates heat and light. In this sense, it makes water due to the temperature gap between inside and out of product. We were inspired by the shape of dew falling like a water drip.
