It's a video of someone removing a cork from a wine bottle using a shoe.

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.
