[W126 Coupe] tornado air twister

[Axel Wulff]

Ah, yes, fluid dynamics.

My favorite liquid for demonstration purposes: BEER

Normal operation:
Take a beer bottle, remove cap and turn bottle upside down. It is a waste of 
precious beer, I know, but we have to make some sacrifices for science. To 
make you feel better, use the kind of beer you don't like (In my case that 
would be any light beer) or practice with water a few times.
Back to our experiment: Use a stopwatch to determine how long it takes the 
bottle to empty.

Vortex:
Slightly more challenging. Take cap offf beer bottle. Make the beer swirl in 
the bottle and then turn it upside down. Time the event. If you do this 
right, you should see a significant improvement (faster) in emptying the 
bottle.

Turbo:
Very advanced. Experienced scientists only. Take cap off bottle. Put the 
bottle to you mouth and your lips completely around the bottle opening. Use 
your index finger and thumb to secure your lips around the bottle neck, we 
don't want any pressure leaks here, and block the bottle opening with you 
tongue.
Now, in one fluid motion thrust you head back, thereby turning the bottle 
upside down, and swirl the bottle. The pressure in the bottle will build up 
almost instantaneously. The pressure will force you tongue back and the beer 
will "shoot" straight into your stomach.
Have a friend time the event. If executed correctly, it will take less than 
two seconds to empty the bottle. Very experienced users come very close to 
less than one second.

Go science!
