joe, flo and moe all get the same meal. in total it costs thirty pounds, so they each pay ten pounds. when the manager sees the bill he realises that the customers have been overcharged by five pounds. he sends the waiter over to return the five pounds but he takes two pounds of it and returns three pounds to the customers. in total they have now payed nine pounds each.
now 3x9=27 + £2 that the waiter took = £29 where is the extra pound to make thirty????????

I've heard all these doomsdayer cultists talking about the pole shift and the end of the world in 2012. Anyone know what this is or if there's any truth to it?

Recently my girlfriend's dad asked me if it was possible to make a fire powered boat. What he suggested was that a fire be made on a (thick) plank of balsa wood. The fire would be then incased around a chimney (with an air opening obviously).
The chimney's hole would then not be directed upwards but rather sidewards.

I am aware that it is fire on wood, but if the surface is properly treated there would be little issue of burning damage. I am more concerned about whether is is possible to create thrust using just the sidewards re-directed updraft from a fire and not using any steam engine etc whatsoever.

Does anyone also have any other simple ideas on how to make a fire powered boat? ie: not a steam engine, rocket motor, combustion engine, etc.

Thanks
H
