What is this thing 是 reddit 上的一个社区（community），上面时不时会有人发一些没见过的玩意来提问。
一起来看看吧！
飞机零件
Q: Any guesses as to what this plane part is? Fell out of the sky in Colorado when that United engine failed.
大家能猜一下这是飞机哪部分吗？因为联合航空的飞机引擎故障的时候这东西正好从科罗拉多的天空坠落。
A: I think that’s a vape pen dude.
我想这就是个电子烟，兄弟。
奇怪的草地
Q: What would cause my friends lawn to look like this after the snow melted.
是什么原因导致我朋友的草地在雪融化之后变成了这副样子？
A: That’s some major vole activity. They look a lot like mice, but tend to be very active under winter snows and like tunneling.
这是田鼠的主要活动轨迹。它们看起来很像老鼠，但是它们往往在冬天的雪下非常活跃，喜欢挖隧道。
金属球
Q: Metal sphere with russian writing found on a Bahama beach.
巴哈马海滩上发现的带有俄罗斯文字的金属球。
A: Its a pneumatic accumulator tank of engine control system of Soyuz rocket. Somebody point it here in comments. http://joyreactor.cc/post/3388576#comment15651851
它是联盟号火箭发动机控制系统的气动蓄能器油箱。有人在这条评论里面提到了它。http://joyreactor.cc/post/3388576#comment15651851
emmm
Q: Saw this bulldozer with a giant spike on the front in a meme. Is this a weird forklift? Why does it only have 1 spike then? Is this possibly to push around a very specific type of equipment?
我在表情包里看到一辆前面有个大钉子的推土机。这是一台奇怪的叉车吗？为什么只有一个凸出来的钉子呢？这可能是为了推动一种特定类型物体的设备吗？
A: We have one similar to that at work. The spike is a little bigger and longer, but we use it for moving steel coils around the coil yard.
我们公司也有一个类似的。钉子稍大一些，也稍长一些，但我们用它来在卷厂周围移动钢卷。
矿洞
Q: Found while trail running. What are these things? There’s rotten wood that goes along it that looks cut/altered by man. Would it be for making a flat surface to easily maneuver the mine?
在越野跑时发现。这些是什么东西？沿路有腐烂的木头，看起来像是被人砍过/改造过的。是为了制造一个平坦的地面来方便地操纵矿井吗？
A: It’s a collapsed wood-stave pipeline, it may have been for dewatering the mine.
这是一条坍塌的木板管道，可能是用来给矿井排水的。
折叠门
Q: Door with a hinged section a quarter through horizontally?
在这扇门的四分之一处为什么会安装有铰链？
A: So it can fold around the corner when it’s open, and not stick out into the room
这样的话当它打开的时候，它可以折叠到角落里，而不会伸到房间里。
两个勺子
Q: WITT: Two spoons attached to a wooden handle at the thrift store?
在旧货店发现的一个木柄上绑着两个勺子，这是个嘛？
A: It’s a musical instrument literally called “spoons”. Used as percussion by clacking the spoons together. I’ll see if I can find an example of them being played.
它是一种乐器，名字就叫「勺子」,用勺子和勺子敲击。我看看能不能找到一个他们在玩的例子。
