It’s about the flower of the young men of the Scottish army who defeated the English at Bannockburn. So, more English hating, really.

They used Jerusalem at the Commonwealth Games for the medal ceremonies. And lovely it was too.

Not 'always wanted to know' because I only thought about it last night, but...
What effect on a game would it have if the ball was filled with helium?
I imagine it'd not be correct under the Laws for the weight of the ball, for starters, but would the same strength kick make it go further, would it go higher (would it come back down?!), would it swerve and move more in the air?

Del

that kinda describes one of the games (the ONLY game) I went and watched here...

8500 ft up

goalkeeper punts the ball off the other end of the field almost every time.

did anyone make an adjustment ? nah....

people ask me if I have been to watch a game here and I say yes - twice...

the first and last time..

:D

I suspect he may have watched the beginning (at least) of the film, 'John Carter'...

To answer, imo, all the effects of gravity on the ball, would be lessened.
Newton would have given a better answer, though.

a football is about 22 cm in diameter, which makes a volume of about 5500 cm^3, which is 5.5 litres.
air density is roughly 1.3 g/L, helium's is about 0.2 g/L.
assuming atmospheric pressure inside the ball, by swapping the air for helium the ball will weigh about 6 grams less, on a ball that is between 410 and 450 grams, so the effect would be negligible (about 1%, less than the variability in weight and pressure allowed by the rules).

newton would have used (possibly now outdated) imperial units, though.
