EMPTY A BOTTLE
How long it takes to you to empty a 1,5L bottle full of water?
When you turn down the bottle, give it a swirl. Make sure that you notice the swirling vortex that has formed inside of the bottle.
The formation of the vortex makes it easier for air to come into the bottle and allows the water to pour out faster.
