There was a bloke on TV the other day who pours molten Aluminium down ant's nests. When it all cools down he digs it up and it looks really neat. A three-dee map of the nest. It also solves the ant problem in no small way. Like the powder, it isn't good for your skin.

(SM) I wonder. The ant's nest would have to be very dry or there'd be an explosion of steam, hot metal and pyrolysed ants. Not nice. Where does he get the aluminium from? He could melt down old saucepans, I suppose, but molten aluminimum is hot, 660°C plus, incipient red heat.

[Tuj] No. As a proud shopper at Auchan, though, I have a "Waaouh" card. Because the savings make me say "Waaouh!". Obviously. Yes.

Our local supermarket advertises something it calls a 'Price Commitment'. Since these signs disappear as soon as the so-promoted product increases in price, one has to wonder to what extent this counts as a commitment.

[rab] With the "Whoops!" button, could one undo a winning move? More pertinantly, could one test several options until finding the winning move, if unknown?

[Tuj] (i) Yes and no. (ii) I think so, but would it really matter?

[rab] Yes and no, eh? There's cards close to the chest. I'm too timid to go test it ;)
And regarding the second, in theory, with patience, one could knock off the likes of Mystery Crescent single-handedly.
