It's a video of someone removing a cork from a wine bottle using a shoe. The
cork comes out of the bottle but I don't see how - although I'm not the
world's greatest physicist, of course :-) IMHO the cork, if it moves at
all, should go inside the bottle because (and this is the bit that justifies
it being in a DIY group) it would seem to be the same principle as putting a
hammer head on a shaft, ie, shaft and head travelling downwards, shaft
stops, head carries on downwards and fits snugly on shaft. Wine bottle and
cork travelling in same direction, bottle stops, cork should continue same
way as the bottle, not go in the opposite direction - shouldn't it?

As he says it is the shock wave travelling through the wine that pushes
out the cork.
The cork does not have sufficient mass for your suggestion to move
downwards to any degree. In the case of the hammer head, the head is
much heavier so dominates over the shock travelling up the handle.

Not sure why he demonstrates this on a wall, I think I'll try the floor
first.

I assume the cork has to be in contact with the wine for it to work - it if
were on the floor, there is an air gap!

Seems like the cork, being lighter, gets left behind somehow. We've got
a couple of physics grads on here, so I'm sure an answer will soon be
forthcoming.

GCSE physics. Newton's Laws. Every action has an equal and opposite reaction.
Same reason newton's cradle works.

Bottle in shoe hits wall. Newton's second law tells us force=mass x
acceleration. Wall doesn't move and exerts equal and opposite force on shoe.
Shoe then exerts that force on bottle. Bottle then exerts that force on wine.
Wine exerts that force on cork. Cork will then move out roughly the same
distance that the base of the bottle sunk into the insole of the shoe.

Something like that anyway!

Or more simply: the wine bounces back and nudges the cork?

The important bit is that the wine is an incompressible fluid and that
the initial shock is fast and powerful, the return wave is weaker - it's
expended energy expelling the cork

I was shown this some time ago, but using a towel rather than a shoe. I
rather think that I learnt about the technique from a Greek whilst on a
company course. Possibly the only thing that I now remember from the
course.

The "Constantinesco" bottle opener. Needs to be French wine. If you
try it, you'll find that some bottle shapes (actually the bases) work,
others don't. This suggests that it's an internal shock wave that's
responsible, not just inertia.

Be warned: much modern wine is in lightweight bottles, and the bases
on those can break when you hit them. Mind you, they're probably going
to be screwtop anyway. It doesn't work on plastic corks either, as
those are so tight a fit.

Another method involving shock waves is illustrated on
http://pulsesciences.com/html/CommComponentsGallery.htm (see image 5th
from the bottom of the page). It is one which may well work with
manmade corks, and possibly even with screwtops

Not really my subject - never could handle the equations in physics - but it
looks to me as if others have missed what might be the effect of the taper
of the normal bottle shape. Like a stiletto heel concentrates body weight
into a tremendous force on a small area, hitting the wider area at the
bottom of the bottle, I would imagine results in the force being
considerably magnified by the bottle taper by the time it hits the cork.

Problem of course, with this method, is that corks tend to be used on older
wines that are likely to have sediment, so the last thing you want to do is
hit the bottom on a wall. If it's a home stored wine and the bottle has
been on its side so as to keep the cork moist, there will be a layer of
sediment all down the side which will make a right old mess after any
thumping. But on the other hand home brewing corks are usually rubbish and
will not have been airtight anyway...

Good bottles have both the capacity and the safe pressure in mm moulded
around the bottom. Go for 80mm and above (Anything that has had fizz in
should be safe.) if you are reusing the bottles for home brew, and stick to
screw caps, except on the odd bottle you want to make a show of.

The standard party method of dealing with lack of cork screws, was the
wooden spoon handle or very strong finger method, to push the cork in rather
than out. A tea spoon then holding the cork out of the way for the initial
pouring. More stylish was the excellent 'corkette' in the pocket, 'just in
case'. Shame that my one stopped pumping eventually, and they don't seem to
make them any mo too dangerous I suppose.

For that I just love to use the modern wrap around and lever action ones

Don't have this table top one, but, if the kitchen wasn't already

I reckon everyone else drinks cheap filtered wine, not the real stuff.
That bothered me too.

I reckon its the shock wave travelling through the incompressible fluid
(wine) causing a temporary increase in pressure against the cork

I've seen it done before - I attended a martial arts club in Indonesia
and one of them was showing me a few tricks. He thumped base of the
bottle with the palm of his hand and drove the cork out. I tried to
repeat his trick but couldn't . I can only think that my speed and focus
were not sufficient to do it

used to be a bar trick, where you would bet you could burst the bottom out
of a beer bottle by hitting only the top.

You drank some of the beer ... (at least 3/4 full) held bottle firmly, and
give the open neck a hit with the heel of your palm ... as hard and fast as
you can.

The speed of blow caused a compressed air 'wave' to move into bottle, hits
beer, which can't compress, and in turn send force by hydraulic through the
bottle forcing bottom out of the bottle.

The important part is the strike must be very hard and very fast the first
time ..... otherwise, it just hurts, followed by repeated attempts as they
get embarrassed each one only succeeding in developing a monster of a bruise
to hand & ego.
