«The apple experiment» is finished
Since the little bugger wasn't moulding after a considerable time-span (5 months!), I eventually ate it last week in a peculiar hunger attack . Luckily, I was smart enough to collect photographic evidence about my mission, as «some» folks have taken my alleged secretiveness as a serious affront.
About the culinary experience: admittedly, it was a little to sweet for my taste, but what do expect after somewhat more than 5 months of ripening?
 I can see the next Sun headline: «Poor student had to eat decaying apple! Authorities are shocked!»
