“罐头盖子打不开怎么办”、“裤子上沾上了墨水要怎么洗”、“怎样切洋葱不辣眼睛”……这些生活问题在每个人的生活都会遇到。外国网站Reddit搜集了25个网友们亲身试验过的25个生活小技巧，简单又实用！如果上课或者开会时昏昏欲睡，把你的一只脚稍稍的抬离地面，看能坚持多久，你就不困了。Use shaving cream as anti-fog. I used it on the inside of my motorcycle visor. Smear it on, let it dry, then rinse off and dry. It also works for bathroom mirrors. You can use it on a small spot so you can still see when you get out of the shower.剃须膏可以用来当防雾剂。把它抹上在摩托车遮阳板的内侧，晾干，冲洗干净，再晾干。浴室镜子起雾也可以用这个方法，把剃须膏涂在镜子的一块地方，洗完澡镜子还能看清楚。
对着吸尘器大喊，这样你们家的狗就不会朝着吸尘器狂吠了。@omgIamafraidofreddit / RedditThat rubbing alcohol removes chewing gum. I’d go through a 20-layer-deep marketing funnel to get to that tip because it really does work.医用酒精可以去除口香糖。即便要经过20层劫难才能得到这个经验，我也会去做。因为它真的有效。 @Djason_Unchaind / RedditYou can do the Heimlich maneuver on yourself. Use a chair or countertop, press yourself against it (right under your rib cage), and press down hard. Should force air up and dislodge a blockage.你可以给自己做哈姆立克急救法。用一把椅子或者工作台，把自己压在上面(放在你的肋骨下面) ，然后用力一压。这会迫使空气上升排出堵塞物。@SnooPickles3213 / RedditThe cheapest, most effective, and safest insecticide against roaches (especially those huge “water bug” roaches that we have in the South) is a spray bottle of mostly water with just a little liquid dish soap in it. Shake the bottle and get the water a little foamy, then spray the roaches. They will run, scramble, and attempt to escape, of course, but they will die. The soap film suffocates them faster than any chemicals will. Plus, it’s very easy to clean up and is safe around food (not that you want to spray soapy water ON your food).对付蟑螂（尤其是南方那些巨大的 '水虫 '蟑螂）的最便宜、有效且安全的杀虫剂是一个找喷雾瓶，里面放满水，滴几滴洗洁精。摇晃瓶子产生泡沫，然后喷在蟑螂身上。蟑螂会逃窜、挣扎，试图逃跑，但它们必死无疑。对蟑螂来说，肥皂膜比任何化学药剂都更致命。而且，这也非常容易清理，即使喷洒在食物周围也很安全（不是要你把肥皂水喷在食物上）。
如果你的戒指被卡住了，滴几滴windex(国外清洁剂品牌）就能顺利取出来。我在珠宝店5年多的工作经历教我的。From the amazing book, The Gift of Fear, by Gavin DeBecker: “A woman alone who needs assistance is actually far better off choosing someone and asking for help, as opposed to waiting for an unsolicited approach. The person you choose is nowhere near as likely to bring you trouble as the person who chooses you is.”加文 · 德贝克尔在其著作《恐惧给你的礼物》中写道: “事实上，当女性孤身在外需要帮助时，最好主动向别人求助，而非等待他人来帮助你。因为选择你的人远比被你选择的人更容易让你遭到侵害。Counting really slowly with the goal of reaching 150 is a decent way to fall asleep. If you have any thoughts during it, just let them play out, and if you forget what number you’re on just go from what you last remember. If you make any major movements, just start again. The goal is to force your brain to slow down and not have any jerky motions or thoughts, and eventually, reach such a level of carelessness that you eventually fall asleep without realizing it. Helped me quite a few times, especially with rain sounds. Hope it helps some of you too!睡不着时，慢慢数数字，目标是数到150。如果有其他念头，让它去。如果忘记了数字，就从最后记得的开始数。期间有任何大动作，就重新开始数。这样做的目的是迫使大脑慢下来，不要有任何突然的动作或想法，最终，达到什么都不想的地步，你会不自觉地睡着了。这个方法帮助我入眠很多次，搭配雨声尤佳。希望它也能帮到你们中的一些人！
如果生火的东西全都被打湿了，而你手上只有火柴和零食。玉米片可以当引子被点燃，燃出一团大火。@Lost_in_the_Library / RedditPut your onion in the freezer for 10 minutes before chopping it. It freezes the juices just enough to slow down the process of it turning into a gas, giving you a few minutes to chop the onion without tears. I learned this tip from a kid’s science show years ago and haven’t had to deal with onion tears since. So many people don’t believe me, and they are genuinely surprised when it works.切洋葱之前，把洋葱放到冰箱里10分钟。低温能减缓洋葱变成气体的时间，让你切洋葱不流泪。我是几年前从一个儿童科学节目中学到这个方法的，从那以后我再也不会在切洋葱时流泪了。一开始很多人不相信，但是当这个方法奏效时，他们惊呆了。
Vinegar in a plastic bag with a rubber band tied around any faucet will make the faucet like-new. I’m talking decade-old rust and stuff gone...and water flows like the first day. It also works on showerheads. You can unscrew those and leave them in a bowl full of vinegar.把醋装在塑料袋里，用橡皮筋绑在水龙头上，水龙头会焕然一新。即使是十年的锈迹也能消失不见，水龙头的水流动像第一天那样顺畅。对于清洗莲蓬头也有用。把莲蓬头拧下来，放在一个装满醋的碗里。If your car is overheating, turn your heat on full blast. When you turn the heat on in a car, it pulls heat from the engine into the cab, thus cooling the engine. I was taught this in driver’s ed 23 years ago. When my buddy’s car would run really hot back in high school, I told him to turn the heat on. He wouldn’t. I had to convince him it was true by saying I would pay for the resulting damage if the temp didn’t go down. It was the wintertime, and that heat was so hot we had to roll the windows down. But we watched his engine temp drop. I don’t believe it’s especially uncommon, but if no one ever told you, it would seem counterintuitive. This doesn’t work on electric cars and, depending on your mechanical Issue, it may not work at all. It’s not a permanent fix, this is to get you somewhere to safely address this issue.如果汽车过热，把汽车暖气开到最大。打开汽车的加热器，汽车会把热量从发动机吸入驾驶室，从而冷却发动机，这是我23年前在驾驶课上学到的。高中时，我朋友把车开得过热，我告诉他把暖气打开，他不听。于是我和他打赌，如果温度没有降下来，我赔偿你的全部损失。那是个冬天，当时车内温度太高了，我们不得不把车窗摇下来，我们看着车子温度一点点下降。我不觉得这个方法很少人知道，但要是没人告诉你，你会觉得它违反常识。这个方法不适用于电动汽车。根据汽车机械构造的不同，它有时也可能不起作用。不过这不是个一劳永逸的方案，这是为了让你去某个地方安全地解决这个问题。Clean jewelry with dish soap since other cleaning supplies might scratch it (like hand soap or anything that exfoliates) or chemically react with the metals (usually like harsh cleaning supplies) and dish soap is intended to clean glass and ceramic without scratching it and silverware without reacting with the metal, etc.用洗洁精清洁首饰，其他清洁用品可能会划伤首饰(比如肥皂或任何可以去除角质的东西) ，与金属发生化学反应(通常是刺激性的清洁用品) 。但洗洁精是用来清洁玻璃和陶瓷的，它不会划伤首饰和银器，也不会与金属发生反应。
Run your wrists under cold water or rub an ice cube on your pulse points to cool down all over quickly when you get overheated. It seems obvious but I didn’t realize it until last summer working in a warehouse with no AC.当你特别热时，将你的手腕放在冷水中，或用冰块擦拭你的脉搏，可以迅速降温。这个方法效果立竿见影，但直到去年夏天，我在一个没有空调的仓库工作时才发现这一点。If you’ve written on a dry erase board (or any glossy surface) with a permanent marker (like a Sharpie), just draw over it with a dry erase marker and it will wipe right off.如果你用记号笔在白板(或任何光滑的表面)上写字，笔迹擦不掉时，只要再用白板笔在上面画一下，字就会马上擦掉。
Smell is closely associated with memory. If you’re studying for an exam, buy an odd scented eraser (like pickle scent). Every time you try to memorize something, take a sniff. Take that eraser to the test and sniff it when you’re having trouble remembering an answer.嗅觉与记忆密切相关。如果你在准备考试，买一块气味古怪的橡皮擦（比如泡菜味）。每次背东西的时候，闻一闻。带着橡皮擦去考试，当你记不起答案的时候闻一下就能想起来。
