Canister in the can

This design is to keep food fresh without using electricity.
The design is based on the principle of evaporation and
heat absorption. The product is divided into two layers: inside
and outside. Sand is poured into the two layers, and water is added.
Food is placed in the inner layer. The irrigation mouth is covered
with a wet cloth, which can keep food fresh in the ventilated place.
The function of sand is to absorb heat by evaporation. It is placed in
a dry and ventilated place to accelerate air flow and water evaporation.
