There’s no shortage of products and devices designed to boost our quality of life — whether it’s a self-cleaning coffee maker or a travel accessory that supposedly helps you sleep better while in flight. If you’ve ever purchased something like this, we’re willing to bet you’ve only used it once or twice. Odds are, it now sits unused on your shelf.

不乏旨在提高我们生活质量的产品和设备——无论是自清洁咖啡机还是据称可以帮助您在飞行中睡得更好的旅行配件。如果您曾经购买过类似的东西，我们敢打赌您只使用过它一两次。很可能，它现在在你的架子上闲置着。

Coin of Harmony, however, might be something you’ll use on a regular basis. Invented with the goal of purifying water, the portable coin (it’s small enough to fit in most water bottles) is made of silver and copper and couldn’t be easier to use. Both metals are known for their antimicrobial properties that, when released into water, can help attack bacteria and viruses. That's why the materials have been used for hundreds of years as a way to keep water clean and safe to drink.

然而，和谐硬币可能是您经常使用的东西。这种便携式硬币的发明目的是净化水（它足够小，可以放入大多数水瓶中），由银和铜制成，使用起来非常方便。这两种金属都以其抗菌特性而闻名，当释放到水中时，可以帮助攻击细菌和病毒。这就是为什么这些材料数百年来一直被用作保持水清洁和安全饮用的方法。

You may have read about this idea in history class. American pioneers supposedly placed silver or copper coins in water barrels to ensure the contents remained drinkable. Silver, instead of dangerous lead, was eventually used to create utensils. NASA has even researched silver as an antimicrobial agent; those findings then informed ways the technology can be used commercially (in hospitals, pools, in-home water filters, etc).

您可能在历史课上读过这个想法。据称，美国先驱者将银币或铜币放入水桶中，以确保里面的水可以饮用。最终，银取代了危险的铅，被用来制造器皿。美国宇航局甚至研究了银作为抗菌剂；这些发现随后为该技术的商业应用提供了信息（在医院、游泳池、家用滤水器等）。

Coin of Harmony is the latest iteration.

和谐币是最新版本。

The product instructions are relatively straightforward. You just need to place one of the coins in any water container (like your go-to water bottle for workouts, the jug in your refrigerator, or that hiking backpack you have yet to clean), fill it up, and give it a shake or two. After that, the water is said to have gone through an effective natural purification process. You can leave the coin in the bottle for the following refills.

产品说明相对简单。您只需将一枚硬币放入任何水容器中（例如锻炼时常用的水瓶、冰箱中的水壶或尚未清洁的远足背包），将其装满，然后摇晃一下或两个。之后，据说水经过了有效的自然净化过程。您可以将硬币留在瓶中以供下次补充。

While Coin of Harmony is easy to use, the company warns the product has the potential to be swallowed, so they advise keeping it out of reach of smaller children or anyone else who may be at risk. It also notes that the coin is built to last for several years, but continuous use may result in the Coin of Harmony turning slightly darker on the copper side (the patina process) and possibly foggy (or tarnish) on the silver side.

虽然 Coin of Harmony 易于使用，但该公司警告称，该产品有可能被吞咽，因此他们建议将其放置在较小的儿童或任何其他可能面临风险的人接触不到的地方。它还指出，该硬币的设计可以使用数年，但连续使用可能会导致和谐硬币的铜面稍微变暗（铜绿过程），银面可能会变得模糊（或失去光泽）。
