We're gonna just use some regular pepper, have it float on top of some normal deionized water.

我们要用一些普通粉，让它浮在一些普通去离子水上面。

That could happen if stocks of AdBlue, a mix of urea and deionised water that neutralises nitric-oxide emissions from diesel engines, are depleted.

如果 AdBlue 库存耗，尿素和去离子水混合物可以中和柴油发动机排放一氧， 会发生这种情况。

The best water to drink would actually be distilled water or deionized where everything's pulled out.

最适合饮用水实际上是蒸馏水或去离子水，因为其中所有杂质都被去除了。
