How a zipper works

This is relaxing to watch

You can see the clasps coming down or the zipper going up :p

That's trippy.

Thats a long zipper

That's one long jacket

Me can watch this for hourssss

Long coat

nooooo, thats totally badass!!!!! O_o

I can watch this for ages!

How in the f**k do I end up with with one side an inch lower than other side, trapped in my hoodie?! Seems to be a precision marvel from the future.

This reminds me of what we had to watch in Biology class about DNA.

Oh my god! Thank you kind sir or madam! I've never known how this worked

This just made my life so much easier

this is so satisfying you have no idea
