I was asked what the most expensive liquid is the other day. I came up with an answer but I wasn’t sure if it was the *most* expensive. Can anyone suggest expensive liquids?
Examples:
– gas $US3.30 per gallon
– milk $US2.30 per quart
– bottled water $US$ per 600ml (at the picture theatre)
Notes:
– Monetary units per unit volume
– Don’t worry about currency / national differences (ie petrol / gas)
– place of purchase shouldn’t determine most expensive (it will have an impact, but not in the final consideration)
– Liquid at standard room temp – thus ruling out (for example) molten gold
