Grow and reproduce. Jujubes are stored in water for too long, will ferment to produce a large amount of gas, due to the good airtightness of the glass, the gas is constantly expanding in the cup, so that the pressure in the cup increases, the glass itself is not a high-pressure resistant container, when inside

When the air pressure is too high, the glass will swell.

Water refilling: It is recommended to add water less than 20mm away from the cup mouth to avoid overfilling and burning the lid after overfilling; When filled with water, the lid should not be over-locked to avoid damaging the bottom of the liner.
