这个聪明的冰箱黑客使用一枚硬币和一杯水来检查停电期间的食品安全

该视频因其非常简单实用的方法而广为流传。那么，这是怎么回事，为什么人们如此着迷呢？

A TikToker recently shared a clever hack for checking freezer safety during power outages, and it's quickly gone viral for its simplicity and practicality. The hack involves filling a glass or container with water, freezing it, and then placing a coin (or another small item) on top of the ice. If a power outage occurs and the freezer's contents thaw, the coin will sink into the melting ice. When the freezer refreezes those goods after a power outage, the coin will be trapped inside the ice in a new spot, letting you know the food thawed and may not be safe to eat.

一位 TikToker 最近分享了一个在停电期间检查冰箱安全的巧妙技巧，该技巧因其简单实用而迅速走红。该技巧包括在玻璃杯或容器中装满水，将其冷冻，然后将一枚硬币（或其他小物品）放在冰上。如果发生停电并且冰箱中的物品解冻，硬币就会沉入融化的冰中。当冰箱在停电后重新冷冻这些物品时，硬币将被困在冰内的新位置，让您知道食物已解冻，可能无法安全食用。

TikTok creator Daivi (@Daivifromkajustudios) introduced this helpful trick in the viral video, which has amassed nearly 365,000 likes and almost 30,000 shares. The concept is simple: Fill a glass or container with water, let it freeze, and then place a coin (or other small item) on top of the ice.

TikTok 创作者 Daivi (@Daivifromkajustudios) 在这段病毒视频中介绍了这个有用的技巧，该视频已获得近 365,000 个点赞和近 30,000 次分享。这个概念很简单：在一个玻璃杯或容器中装满水，让它冻结，然后将一枚硬币（或其他小物品）放在冰上。

"It's actually a really good life hack," Daivi explained in the video. "If at any point that quarter falls within the water and refreezes, you know that at one point, your freezer was warm enough for everything to thaw. Hence, the food is not safe to eat."

“这实际上是一个非常好的生活窍门，”戴维在视频中解释道。 “如果在任何时候该四分之一落入水中并重新冻结，您就知道在某个时刻，您的冰箱温度足以让所有东西解冻。因此，食物不安全食用。”

The creative hack offers not only practical advice but also a bit of levity in a frustrating scenario. Whether you use a quarter, a penny, or even a gum wrapper, this hack reduces guesswork when it comes to food safety because it provides a reliable way to determine whether your food has spoiled during a power outage, helping families avoid foodborne illnesses.

这个创造性的黑客不仅提供了实用的建议，而且在令人沮丧的场景中也提供了一点轻松。无论您使用 25 美分硬币、1 便士，甚至是口香糖包装纸，这种技巧都可以减少食品安全方面的猜测，因为它提供了一种可靠的方法来确定您的食物在停电期间是否变质，帮助家庭避免食源性疾病。

It's ideal for those in areas that experience frequent power outages or extreme weather, which has become more intense and frequent with the rising global temperature.

对于那些经常经历停电或极端天气的地区来说，它是理想的选择，随着全球气温的上升，这种情况变得更加严重和频繁。

The U.S. Department of Agriculture explains that perishable items left in an unpowered refrigerator for more than four hours should be discarded, and frozen food that reaches above 40 degrees Fahrenheit can't be refrozen. This often leads to significant waste during extended power interruptions.

美国农业部解释说，在未通电的冰箱中放置超过四个小时的易腐烂物品应该被丢弃，并且温度达到 40 华氏度以上的冷冻食品不能重新冷冻。这通常会在长时间断电期间导致大量浪费。

Smart home solutions (including solar combined with battery storage) can complement tricks such as this by boosting climate resiliency and minimizing waste during outages (while preventing potential stomachaches).

智能家居解决方案（包括太阳能与电池存储相结合）可以通过提高气候弹性和最大限度地减少停电期间的浪费（同时防止潜在的胃痛）来补充此类技巧。
