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?



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.
