I know you don’t care about this

But I wanted to know. 

According to Kate Ascher’s book “The Works”, those silver tanks on the street hold liquid nitrogen at 300 degrees BELOW zero.

It’s so cold the gas turns into liquid.

Under carefully monitored pressure it flows down a rubber tube, into a manhole and then enters the insulation around underground data cables.

It warms up to 280 degrees BELOW zero and becomes gas then flows around the data lines, pushing water vapor out and keeping them dry.

All that just so you can tweet and post to instagram.
