Science Channel can dramatize anything

[henhen]

He didn't mention how the S bend keeps out the smell by keeping water there to block the sewer smell from coming through. Or the fact that pressure generated is due to the height of the water in tank. :|

Everyday things that we don't really think about are actually the most interesting.

I was laughing way too hard at that CG break down of the toilet.

[neha]

I've always wondered how they work. It looks like such a basic thing, but it actually seems pretty complex! Thanks for the video!

[zhronic]

I love how they are making this seem so remarkable

[elettrofans]

My shit need a full buckle of water to go down, the flush isn't enough

[louismccall]

Dramatic... But entertaining and exactly what I needed

[alberttarimo]

bro you didn't have to go so hard on the effects like that

[NextLevelNoob]

This is actually pretty impressive techonology-wise, it is probably the most underrated technology.

[RealSkyDiver]

but doesn't explain how the s-shape comes into play to flush the water down instate of simply shitty explanation (no pun intended)

[Evan]

[rhyegianariola]

I never knew learning about toilets could be interesting

[jorostuff]

That was the most epic presentation of a toilet

[azeez]

Never thought learning how a toilet flushes would be so epic, lol.

[mocabe]

Kudos to the humble toilet! Fantastic animation, SC !!!

It’s the middle of the night and I can’t sleep.
So I’m watching a video about how toilets flush and I’m fascinated. So much so that now I’m afraid I may never fall asleep.
God bless all of the toilet-makers out there. God bless them, every one.
