When cooking at home, especially if you're in a hurry, it can be tempting to pour leftover grease or oil down the sink.
We all know that we're not supposed to do it but sure look, we're only human.
That said, we will never EVER do it again after being traumatised by this video posted by Business Insider.
The video shows what happens to the grease once it goes into your pipes and the sewer system.
Spoiler: it's not pretty.
