I was snorkelling at the weekend and saw a bottle of beer on the sea bed with the top on, I went down to have a look and sure enough, it did. I let it drop back to the sea bed, vertically, neck up, expecting it to hold that position the entire way, but it didn't, it turned sideways, and fell the entire distance sideways, straight down, without any wobble, or instability. Wow I thought, a bottle of beer, falling through water, has LESS drag falling sideways then length ways? I was surprised. Can anyone suggest a reason why this should be?

What I can't figure out and what suprises me is the fact you left the bottle of beer behind :doh:
It was a good few months old IMO. I didn't think it would be that drinkable. :)

To misquote George Banks: "... rendering the beer undrinkable, even by Americans."
You'll never get very far if all you do is follow instructions.

You could have Nagy do a taste test.

Reminds me of a discussion (argument) which may have happened in real life or perhaps even here. Why do Champagne bottles (except Cristal) have concave bases? A. For strength B. For stacking C. To make the bottle appear bigger Genuine question, I can't remember the answer.

not at all, only to put the thumb in its ass for serving it... "A flute of champagne must be filled with elegance! As well as the opening of the bottle, Champagne service has its ritual which contributes to the pleasure of the guests. To be paid, the Champagne bottle can be held in the Middle full hand (as is done for other wines). It is also very convenient, especially for the magnums, grasp the bottom of the bottle, right hand thumb introduced in flare and other fingers stretched under the base of the Bole, the other hand gently supporting the neck." Exactly what I say shortly! :-\ http://www.maisons-champagne.com/encyclopedie/vignes_au_plaisir/servir_champagne.htm[^]

I'll take a stab. The bottle has less drag falling sideways (smooth shape) than it does with the bottom first (square shape). Dave.

It must have. What is odd is that there is so much less drag despite the massive increase in frontal are when falling sideways. I wish I could find a pic of a bottle falling in air, from a great height, to see what attitude it adopts. It might indicate an effect of boundary layer flow is playing a part.
