“You can force water out of a bottle as fast as you want. Draining upside with gravity requires displacement of air which is why it is so slow, because the air bubbles force themselves up through the same opening as the water and therefore cut off the flow. This isn’t an issue if you’re crunching a bottle together as the water ejects. There’s no need for air displacement because the volume of the bottle decreases at the same rate as the water. Could be fake, but it’s definitely possible to do.” — Dan428
