What happens when you're the only one who doesn't smoke in a dorm full of smokers? You build yourself this device to let you breathe some good old clean air. This Chinese college student in Nanning City set up a 'respiration device' in the dorm he shares with smokers.

It looks like it's pretty well thought out.

And also kinda crazy.

He can only breathe clean air when he's at his workstation.

The duct is made up of a series of plastic trash bags duct taped together.

It leads to a fan by the opening above the door.

So finally, he's breathing some clean air.

All good now.
