A fire pit, not quite completely encircled by a C-shaped bench which runs on circular rails, so as to rotate freely around the fire.
A large weathervane sits atop the whole assembly, attached to the bench by stout poles, so that as the wind changes direction, the bench rotates, and nobody has to get
up and move out of the path of the smoke.
Condensed Milk
http://en.wikipedia...wiki/Condensed_milk
It turns to baker's caramel if you heat it for about 20 minutes by boiling the unopened can in water. [UnaBubba, Apr 25 2012]

//not quite completely encircled// You do realise that convection causes the hot air to rise, drawing in cold air though the gap, and so spreading smoke in every direction except the gap? |
|
| |
I thought the gap was just to allow access to deliver more firewood rather than redirecting airflow - although that would mean forcing your way directly through the thickest smoke. |
|
| |
The idea is that the gap corresponds to the bit of ground that nobody wants to sit on because the smoke's blowing that way. |
|
| |
I wasn't thinking of it being particularly high off the ground - the main obstacle to the airflow would be the people sat on it. |

A La-z-boy invention for cavemen. I like it. |
|
| |
I liked this one because it made me laugh; it's one of those that's such an expensive and complex solution to such a stupid, trivial problem |
|
| |
[Idschler], I believe that would be a La-z Susan, not
boy. But I say that with all due respect. |

<Surreptitiously tosses a half dozen cans of
condensed milk into firepit and saunters off, to
watch for explosions from a safe distance.> |
|
| |
Condensed milk or milk powder? |
|
| |
I don't think powder would do much. |
|
| |
Actually, powdered milk burns like merry hell. I assumed
that was what [UB] meant. |
|
| |
Nah, 'cause they condense all that milk into a little can, so when it expands to it's original volume it goes 'boom!'. |
|
| |
Powdered milk burns like dairy hell. COW-BLOOM! |
|
| |
Condensed milk is milk solids and sugar, in a syrup.

| |
When the can overheats it explodes and sprays
everywhere. It also sticks like napalm. |
|
| |
Powdered milk, like flour, is explosive if you disperse
it in air and ignite it. |
|
| |
You are correct. Cornflour is best. |
|
| |
// When the can overheats it explodes and sprays everywhere.//
It is quite difficult to get one to burst though - over an hour in boiling water is easily withstood. (toffee ice-cream..mmmm) |
|
| |
Well, you'll never burst one in boiling water, but they'll certainly burst on a fire. Also, see Mythbusters for what happens when you drop tinned goods into boiling oil. Very, very scary. |
|
| |
That's why I suggested tossing them into the fire,
[spider]. We accidentally let two boil dry in a billycan
over a campfire, when I was in Scouts, in the 70s.
We came back to a camp that was festooned in burnt
toffee. |
