When drinking water from a silver cup, silver ions can be dissolved in water, and when they meet bacteria, they will be adsorbed on it, so that their colloids will converge and solidify until they die. This is what people often say: "Silver has bactericidal effect". Silver is a natural antibiotic. Generally, antibiotics only act on 6 kinds of bacteria on average, but silver can destroy 650 kinds of bacteria, and silver ions can weaken the enzymes that do activity in bacteria.

Precautions for using silver cups:
1. Do not pour boiling water directly before use. The inner container of the silver cup will be deformed due to thermal expansion and cold contraction, so it should be preheated by pouring 60-degree hot water first. When the temperature of the cup is hot, you can pour boiling water, which can eliminate the stress change caused by thermal expansion and cold contraction.
2. After pouring boiling water, don't tighten the lid to prevent the liner from deforming. The correct way is to screw half the lid first, but not the rest, so as to prevent the inner container from being deformed due to uneven internal and external pressure and avoid the disadvantage of not being unscrewed.
