I stared creepily at the video, watching it over and over.
First attempt on back of a mug with a pie slicer... could see possibilities, but the icecream kept trying to slide off the mug back.
Second attempt on an icecream cone, with softened icecream and cake slicer - icecream was too soft, would not hold structural integrity, though the intentions could be seen.
This is my third attempt! Where the thing, while obviously crafted by an incompetent nugget, definitely has hints of where it COULD go...
Moohaha. ONWARDS! FOR SCIENCE!
Also has the interesting side-effect of giving the icecream a 'fluffier' mouthfeel. And, enthusiastically related by Nuggetboy (I prefer making icecream to eating it, so he has eating duties), 'Ooh this is great it goes all the way to the bottom of the cone!'
