A cat, trying to drink water from a kettle

newtboyjokingly says...

And it blows!

Smart cat. If only the lid were sealed his blowing through the spout would have pushed the water up the spout where he could drink. HALP HIM HOOMAN!

BSRsaid:

Well, that sucked.

I thought the same thing but remembered water seeks its own level

“Water seeks its own level” is an expression referring to the fact that if water is free to move than all surfaces exposed to the atmosphere will be at the same height. That is the lowest energy state; potential energy is released when water at a higher point flows down into the depression

Yes…Unless acted on by some outside force, like unequal pressure between the now pressurized interior of the kettle and the exterior atmospheric pressure. When he blows air in (see it bubble) it would pressurize the kettle body (if the lid was sealed) and push the water in the spout above the level in the body.

I could see the vent holes and perhaps the not quite sealed lid was working against the cats efforts. This is why cats need to start chewing gum.

Oh…my mistake, I didn’t recognize them as vent holes…
(switches to Werner Herzog voice)
….so it seems the lid will never seal and the cat shall die of thirst millimeters from its salvation. Yet another senseless death in a cruel senseless world.
