I recall seeing this "invention" on the late lamented "Tomorrow's World" about 3 yrs ago. It was demonstrated by using an Apache - in the UK. (Last known sighting
)
Whirlyglug - you are of course right. So keep taking the Pinotage. (While you're about it, try a bottle of NZ Peloris which is way better than many champagnes and about half the price. Majestic have it.)
