今天网上在传一个很火游戏——立扫把，说2月11日也就是今天是地球引力最小的一天，扫把可以立起来。网上还有立剪刀，立刷子，立牙签……总之看着都好神奇。在好奇心的驱使下，我和妈妈也试了一下立扫把，还真立起来了，这是为什么呢？我和妈妈都非常疑惑，连忙上网查了一下，我查到说是因为只有2月11日地球引力会变大，所以扫把可以立起来，而妈妈查到的却是相反的说只有2月11日地球引力会变小，所以扫把可以立起来。到底是因为什么呢？可惜已经很晚了，我们只好先上床睡觉，明天再找答案。
There is a very popular game circulating online today; — Stand up a broom, saying that February 11th is the day with the smallest gravitational force on Earth, and the broom can stand up. There are also upright scissors, upright brushes, and upright toothpicks online; … Anyway, it looks so magical. Driven by curiosity, my mother and I also tried standing the broom, and it really stood up. Why is that? My mother and I were both very puzzled, so we quickly searched online. I found out that it was only on February 11th that the Earth's gravity would increase, so the broom could stand up. However, my mother found the opposite, saying that only on February 11th would the Earth's gravity decrease, so the broom could stand up. What exactly is it because of? Unfortunately, it's already late, so we have to go to bed first and find the answer tomorrow.出自 wwW.zuoWEnBA.nEt
第二天一早，我们又兴致勃勃地上网查找相关资料，弟弟淘气地拿来扫把，又立起来了！“怎么今天扫把还能立起来？网上说昨天是唯一一天可以立扫把的日子啊？什么情况？难道有时差？”妈妈皱着眉头疑惑不解。“那我们晚上再试试看呗！”我笑着回答。同时我们又开始查找相关资料，我了解到地球引力近似被看作重力，正是根据重力不变原理，人们才发明了称。试着反推一下，如果2月11日地球引力会改变的话，物品的重量就也会改变了。难道2月11日所有的称都会不准？可惜昨天没有称物品重量来验证。
The next morning, we eagerly searched for relevant information online again. My younger brother mischievously brought a broom and stood up again! “ Why can the broom still stand up today? Is it said online that yesterday was the only day when a broom could be erected? What happened? Is there a time difference? ” Mom frowned in confusion. “ Let's try again tonight! ” I answered with a smile. At the same time, we began to search for relevant information. I learned that the Earth's gravity is approximately regarded as gravity, and it is based on the principle of gravity invariance that people invented the concept of gravity. Try to backtrack, if the Earth's gravity changes on February 11th, the weight of the object will also change. Will all claims on February 11th be inaccurate? Unfortunately, the weight of the item was not measured yesterday for verification.
抱着遗憾的心态，好不容易熬到了晚上，我们再试着把扫把立起来，结果还是轻而易举的成功了。说明网上说的2月11日地球引力会改变的说法不成立，那么扫把可以立起来的真正原因是什么呢？可能由于游戏太火了，很多科学家都来解释了，我很轻松就找到了答案——原来是重心，只要足够有耐心找到物体的重心，且重心有支撑，那么什么都可以立起来，扫把当然没问题啦！
With a regretful attitude, we finally managed to get through the night and tried to stand the broom up again, but the result was still an easy success. The online claim that the Earth's gravity will change on February 11th is not valid, so what is the real reason why the broom can stand up? Perhaps due to the popularity of the game, many scientists have come to explain, and I easily found the answer; — It turns out to be the center of gravity. As long as you have enough patience to find the center of gravity of the object and it is supported, then anything can stand up, and of course, the broom is no problem!
经过这次小游戏的探究，我还知道了一个道理：凡事都要自己动脑，不要轻信谣言！
After exploring this mini game, I also learned a truth: you have to use your own brain to do everything, don't believe rumors easily!
