Opening Wine without a corkscrew

I've not seen this technique before, but apparently it works because of the pressure hits the wine, that hits the air and the air pushes the cork out. Rather neat I think, and not likely to cause damage.

Just to note: people have done tests on corks vs alternative stoppers and broadly speaking, for young drinking wines screwcaps are just as good as corks, don't need a corkscrew and don't have the problem of cork taint that natural corks can get. The writer Jancis Robinson has a comprehensive article about the ups and downs, if anyone's interested.
