Waterbed. A sufficiently large aquarium would outweigh one, but those
aren't very common.

A car or similar vehicle.
Assuming that the garage forms a part of the house, that is.

What if you were having a bath and also had a big hot

A full bathtub. I'm pretty sure that more houses have bathtubs than

I just looked at the tub in my bathroom, and it's *maybe* 56" x 24" x
12", at least the part that holds water. If I'm generous and increase
those dimensions, I can get to 12 cu.ft., which is about 90 gallons US.
With one US gallon being 8-1/3 lbs., that's 750 lbs, or under 350kg.
The car would be heavier if it counts as part of the house.
As for whoever guesed the air, it's about 1.2kg/m^3 (at sea level).
Figure out the size of an average house, and you can figure out how much
the air weighs.

Does a bookcase full of books count as one "thing"? Even if it
does, I'm not sure how it compares to the legendarily heavy piano,
but I suppose the latter is not likely to be in the average house.
(I'm not even sure if the former is!) I'm not thinking outside
the box here, so I know it's not the answer, but I'd like to know
anyway.

If not, bookshelves (including the books) are quite heavy. As are

Only if your idea of an average house is pretty large. My house has
a total floor area of about 1500 square feet, hence a total volume of
something under 12,000 cubic feet. That's only about 400 kg of air,
much less than a car.

Household water. Each year, a house probably has about 60 tons per person.
True. I think a tub or waterbed represents the 'densest' mass in the
house, not the heaviest. Probably the mass of the humidity in the air
or something.
--riverman
The answer I was thinking of is indeed the air. At 1.225Kg per cubic metre
this can weigh nearly half a ton in a smallish house and a ton or so in a
large family house. More than the water in a bath or loft tank or any other
"normal household thing" which doesn't btw include cars and grand pianos.
We rarely even think of air as having weight but it's quite surprising how
heavy it actually is. The air in my lounge which is 14ft x 24ft x 8ft weighs
more than me. The air in the Royal Albert Hall which has a volume of 3.5m
cubic feet weighs 119 tons.

Then it depends on the size of the house and the weight of the waterbed,
assuming the house has one in it. Waterbeds can weigh anywhere from 90
to 800 Kg, which could be more or less than the weight of the air.

No, but it does have a car. The only question is whether it's kept inside
the house or not. Attached garages are very common. I stand by my answer,
which, incidentally, also better meets the "outside the box" hint since
people might fail to *think* of the garage as being part of the house.

Does a garage count as part of the house? If so, then the answer is
obvious.
If not, is a cast iron bath tub or granite counter top part of the
fabric of the building? If they are disqualified, then I'd say fridge.

>If "air" is acceptable as a "thing", them my answer is "atoms",
>which can also be considered a "thing".
But shouldn't "thing", in this context, and at that sort of level
of detail, mean something more like: "the set of all molecules in
some connected regular open set of space-time point events, moving
only slowly relative to the reference frame of the house, contained
within the approximately and conventionally established boundary of
the house, and maximal according to some arbitrary but common-sense
physical restriction of the kind of molecules in question"?
(Approximately.) :-)
(You can probably leave out the bit about "moving slowly", and in
compensation, sharpen up the bit about being contained within the
boundary of the house, specifying some human-scale time interval.)
Then one atom (or molecule) doesn't satisfy the condition - nor
does just any old set of atoms you might mention, such as perhaps
some passing blast of cosmic radiation* caused by diminished sunspot
activity - whereas the set of molecules belonging to the main body
of the air inside the house (excluding pockets of air inside sealed
containers, and so on) does satisfy it (with hindsight). I think a
bookcase tightly packed with books would also satisfy it - although
if you were to run an electron microscope over it, who knows? The
ghosts in a haunted house wouldn't satisfy it; and anyway, they must
be pretty light.
(* OK, so cosmic ray particles aren't strictly "atoms", but you
probably weren't being fussy. We can forget about neutrinos, too
- anyway, they're really not very heavy at all.)

That's just a minor technical problem. The metals don't sink, do they?
Of course, it's not as dramatic as this:
<http://www.youtube.com/watch?v=896vJj6eWYw>
That, or freeze the water, and nothing will sink into it. :-)
None of which are likely to be found unbound and uncontained in an
average house.
Sodium certainly floats. Drop a bit of it in the water and it rockets
around the surface, shooting flame.

That has nothing to do with whether the metals are less dense than
water.

A lot of us thought that was stupid of them, but it is a pronunciation
listed in dictionaries, so some people have used it in real life. And
Doc Brown was familiar with the term in the 1950s, which means he was
using it before it became widely known and people settled on the hard-G
pronunciation. The soft G does make sense, considering that the word
derives from the same root as "giant" and "gigantic". In short: no error.
Just don't ask for a Tab until you buy something.

IMHO "j"igawatt is in fact correct, the initial "g" probably
deriving from "géant" or a close cognate. This is one of those cases
where being right invites ridicule.
For our next test, we will ask a randomly chosen group of Merkuns
to speak the word meaning "one thousand meters" (not "metres," because
they're Merkuns). Having heard their answers, we will then ask them to
explain "cenTImeter" and "meGAbyte," and we will smirk--until they,
having had more Latin than we anticipated, will retort "HEXameter" and
grind our smirk under their DEparting heels...

OK, now that we've all had our fun, help me figure out what I meant. A
full bathtub isn't the HEAVIEST item, since there are larger items
that weigh more (like the car, for example). Nor is it the DENSEST
item, since (as we have established fairly conclusively, any metal
item in the house is denser). But my point is that it is the densest
item over a large area.....maybe if we multiplied the volume (cubic
cm) by the mass (kilograms), we'd get some sort of scaled density or
something. I don't know what I'm trying to say....but certainly a full
bathtub has more of an effect on the structure of the house than the
faucet, or the air. How can we express that?

I think the car would still win out.

Yes, of course a complete car would sink in a pool. But not every
piece of the car is heavier than an equivalent sized piece of a tub.
For example, the interior....
--riverman
In fact, now that I think about it, I don't think the car would win
out. Most cars float until the water leaks in and fills the interior
and floods the trunk space. If we considered a car to include all the
airspace in its interior, the water is denser.
--riverman
*Multiplying* mass by volume gives a number with no practical meaning.
It would be much larger for the air than for any of the other things
mentioned here.
The "effect on the structure" is mostly determined by two things:
total weight and pressure.
But in both cases you first have to allow for the buoyancy of the
thing in air. In the case of the air itself, the result is zero.
For everything else, the correction is tiny -- for water it would be
0.12% (because air is 0.0012 times as dense as water).
As to pressure, this depends on the areal density of weight -- in
other words, the thing's weight divided by its "footprint" area.
For this measure the greatest value may well arise from people in
high-heeled shoes.

There's this one of a large chunk of sodium being dropped in a lake:

Looks real, but you never know.
Yeah it does. I like seeing that one piece bouncing around...first it
flies up just to the left of the initial explosion and lands on the
far side, then bounces back and lands in the front left side, and then
it flies back over the initial site and lands on the right. You can
see it if you are quick with the pause button.
I think this is real...even the camera iris shuts down when the sodium
