@dgar 😁
So I wake up in my hotel room at midnight to the smell of smoke, remembering about this device I:
Run out of my room to the stairs
Run down 15 flights
Get out onto the street & ask a firefighter for directions to the hardware store
Run to hardware store, buy said device
Run back to the hotel
Wave at the firefighters as I pass them going up the stairs
Stagger into my room
Spend 5 minutes unwrapping device
Firefighters find me with my head in the toilet
Successfully rescued 😜
@dgar The inventor seems to know the smell coming out of a dried out siphon: that's why the nose is being kept out of the airway.
@dgar can breathe, but at what cost
@dgar Hmmm, how do you know the other end of the tube is not under water? Inhaling that kind of water Instead of some badly needed air must be an unpleasant experience

@yourfutureex
I would have to read the actual patent to answer those questions. @thomas posted this link to it in another comment.

@dgar no thanks, I'll take my chances with the fire

@dgar I think I might rather breathe the smoke than the sewer air.

The bathtub in our en-suite went unused for a few months, and the water in the air-lock s-bend evaporated. It took a day or two to work out what the problem was and why the room smelt like shit & death. Poured some water down the bath drain and the smell went away instantly!
Honestly - wrap a wet towel around your head & breathe through that, or just jump from the 15th floor window and hope there's a pool beneath you.

You don’t have to convince me! 🀣
I was mildly amused to find out that its an actual patent application though.
