water cannot be presurized

You don't fill it with water, just add between 1/4 and 1/3 of the bottle's capacity.

If you wanna know why it works, become a physicist or read this wiki.

That's an inflating needle for sports balls, not a "bike needle". I don't know how you could use one on a bike.... :-)

I suppose that you could use it to let the air out of the tires... it's about the right size to depress that little pin.

That would make it an anti-bike needle! (LOL)

This is known in my household as the 'John Noakes Rocket' - Blue Peter, circa 1970. It's one of those 'toys' which has stood the test of time. Try it with a washing-up liquid bottle (with the small nozzle) with around two inches of water inside. (Sticky back plastic is optional #;¬)
