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！
Q: Found this glass like tube “shell” washed up on a beach in North Caroline, any idea what it is?
这个像玻璃管一样的「贝壳」被冲上了卡洛琳北部的海滩，你知道这是什么吗？
A: Stingray teeth
赤魟的牙齿。
Q: Driftwood with metal plaque found on the Mississippi river bank.
在密西西比河岸发现的带金属牌的浮木。
A: Looks like a piece from a bedhead. I think the sheath of wheat is a xtian symbol about reaping what you sow and of death and renewal. Something along those lines. Wheat has been used on double (marital) beds for centuries, including the bedhead and upright posts. They’re also used on chairs in a literal or a stylised way and represent prosperity in relation to the ‘reap what you sow’ type of symbolism.
看起来像是床头的一部分。我认为麦子的鞘是一个关于一分耕耘一分收获，死亡和重生的基督教象征。差不多就是这些意思。几个世纪以来，小麦一直被用在双人床上，包括床头和立柱。它们也以字面或风格化的方式用在椅子上，并代表与「一分耕耘一分收获」类型的象征意义有关的繁荣。

Q: Full tub with deep front half. USA. Listing calls it a mailman tub. Google results in Rule 34.
一个前半部分很深的浴缸，位置是在美国。听说叫做邮递员浴缸，谷歌搜索结果会有色情内容。
A: Probably for washing your feet.
可能就是用来洗脚的。
A: I was thinking feet as well. After all, mailmen have sore feet.
我也在想应该是用来洗脚的，毕竟邮递员的脚很疼。
Q: Found these soft metal objects while metal detecting under a pier at low tide.
退潮时在码头下进行金属探测时发现了这些软金属片。
A: Saw a similar post a few weeks back and I don’t remember what religion but I’m pretty sure they’re good luck/prayer charms that are tossed in the water on purpose. They’re cheaply buyable and have no significance once they hit the water so you can keep them without upsetting anyone, but no, they aren’t ancient.
几周前看到一个类似的帖子，我不记得是什么宗教，但我很确定它们是故意扔到水里的好运或者祈祷符。它们很廉价，随随便便就能买到，而且一旦扔到水就没有任何意义，所以你可以留着它们而不用担心得罪其他人，但不，它们并不古老。

Q: Variable stop sign in Illinois
伊利诺伊州的可变停车标志。
There wouldn’t be another road coming in at a shallow angle to the left of this, would there?
These are blinders, typically used so the sign can old be read from a narrow angle. They’re also called directional shields. You’ll see them on traffic lights a lot more often.

这条路的左边是不是还有另一条以很小的角度并入的路？
这些是遮罩，通常用于标识可以从一个狭窄的角度阅读。它们也被称为方向屏蔽。你会经常在交通灯上看到它们。

Q: A small plastic and metal device, found in the card slot of an ATM
一种小型的塑料和金属装置，在自动取款机的卡槽中发现。
A: Looks like a Lebanese loop to me used in atm fraud, I won’t explain how just tell bank.
在我看来，这是一个用于 ATM 诈骗的黎巴嫩圈。 我不会说明这怎么用，你只需要告诉银行这件事就行了。

6 英寸高，4 英寸宽，感觉像金属，发现于科罗拉多山麓。
