Dealing with high fuel prices

[Duncan Grimmond]

I remember a Chemistry teacher showing us the "quick'n'eazy" way to empty a demijohn bottle with a sudden circular shake. This would start a vortex in the neck of the bottle and it would empty smoothly and fairly quickly.

Oh, and the perennial "secret Government recipe for converting water into petrol with teaspoon of chemicals available for a single penny", supressed by the petrol industry...
