Re: Airbags
For our purposes, these are considered to measure 50 metres long by 25 metres wide and with a depth of 2 metres, containing 2,500 cubic metres of water or, in this case, liquid hydrogen and LOX.

does not quite fit the bill but the question becomes...
Would it be possible, with care, to fill any swimming pool with the required ultimately combustible and stoichiometric mix of Liquid Hydrogen and Liquid Oxygen but, on the assumption that the liquids might be immiscible and can be maintained as liquids despite the temperature differential float one layer on top of the other, add a straw along with a cherry, slice of lemon and a couple of olive's and then, assuming a cool blue colour, upload a picture of Lester sitting by the pool with a big smile on his face in his
y-frontsspeedos with a "12.5 Bulgarian Airbags Equivalent" tattoo on his 'gut'?

subdivided into two tanks - one for the liquid oxygen and one for the liquid hydrogen.
Side note: I've found the shuttle external tank to be an interesting demonstration of just how bizarrely low the density of liquid hydrogen is: the hydrogen tank, holding 100 tons of liquid hydrogen, is twice the volume of the oxygen tank, which holds 600 tons of liquid oxygen at slightly-greater-than water's density.

Needless confusion!?!!?!
Surely, a family sized pool depends on the size and composition of the family.
A family of Chinese dwarfs adhering to the old one-child-per family rule wouldn't require a big pool at all, while a good catholic family with poor dietary habits may need a really big one (probably not far off Olympic size).
Then, you'd think the family would pick a pool depending on budget and what they want to do in the pool.
Too many variables here to consider. I'm confused. I need beer.

Re: Carbon emissions?
That's the nice thing about burning hydrogen with oxygen, all you produce is water, no CO2 at all.
(Of course, manufacturing the fuels and chilling them, not to mention the manufacturing of the rocket will all require a fair amount of energy. And by 'fair amount' I mean, "bloody loads").

Still resisting pressure to go metric...
Scientific American, February, 1866:
"Let Congress pass an act declaring that, after the first of January, 1867, the French system of weights and measures (metric) shall be the legal system of the country".
The Register, March, 2016:
"Let Congress pass an act declaring that, after the first of January, 2017, the Olympic Swimming Pool shall be the legal system of measuring rocket fuel burn".

Family sized swimming pools...
For most of them, they are around 20,000 gallons. This number is needed to calculate the amount of chlorine stuff to add to make the water be nice and blue (not green with algae, which WILL happen if you don't pay attention (been there, done that!).
I'll leave it to others to do unit conversion (metric, or Register as necessary).

Re: Family sized swimming pools...
Second that. Ours, well, the one that came with the rented house, is 85,000 l. Close enough to 20,000 gallons.
It was interesting to work out because it's sort of a 90 degree triangle, but the hypotenuse is 'Z' shaped.
But we digress, as already stated, Olympice Size Pools is a safer measure.
