They're often called " urinal cakes" , and a lot of urinals have them.

它常被称作”便池蛋糕“，这也基本成了小便池的标配。

I can consider a place America's urinal cake and still enjoy the occasional visit. Not this time.

我能把一个地方看做小便池里的芳香剂，但我去的时候也还是尿得享受啊，这次不行。

Today, you might still encounter urinal cakes with this stuff in it, but it's a lot less common.

现在你可能见到过含有萘的芳香块，但其实没那么常见了。

So, I wouldn't advise eating a paradichlorobenzene urinal cake either, no matter how delicious that might sound.

所以就算它听起来还挺好吃的，但是我并不建议大家去吃这玩意儿。

I don't know, maybe it's the fumes from the urinal cakes, but I feel like something is happening between us.

我也不知道为什么，可能是由于小便池里洁厕块产生的烟雾吧但我觉得我们之间有感觉啊。

In the early days of urinal cakes, probably around the turn of the 20th century, the little slabs were mostly made of naphthalene, AKA, olden-day moth balls.

大概在二十世纪初的时候，早期的芳香块主要是萘，也就是以前的樟脑丸。

Many urinal cakes these days are made of a compound called a molecule that looks a little bit like a throwing star and is often used as a naphthalene replacement in moth balls.

现在芳香块的主要成分是二氯苯，一种看起来像是飞镖一样的化学分子，通常在樟脑丸中作为萘的替代品使用。
