Using liquids of appropriate specific temperatures
and densities, design a hurricane in a box: A real
hurricane driven by heat differentials, capable of
condensing something white out of something blue,
with all the same wind effects. Lightning is a big
bonus. Heat the bottom of the box to
keep it
running. (hopefully you won't have to heat it too
much)
Now make the sides and top of the box transparent
and decorate the bottom of the box to look like
someplace.
Put it in your living room.

This is the coolest thing I ever didn't see (in this moment). Bun [+] |

+ I think you can make it like a snow globe and use a mini Van DeGraaff generator for the lightning! |
|
| |
I have actually seen this as a giant glass globe which had, I think, white and blue liquids of the same density that didn't mix. You would spin the globe and then stop it, and all the white clouds would swirl about in very convincing patterns. |
|
| |
Make this happen, please. |
|
| |
Creating your temperature gradient could be problematic. If you think of it as a glorified lava lamp, you need height in order to get your cooling effect and then you need to add some machinery to give your storm some artificial spin as well, so your table might end up more like a large altar. |
|
| |
What if I freeze the top, Dr? |
|
| |
The heat flow rate can be managed by selecting fluids of low specific heat capacity. Unfortunately, this means low density fluids which are unlikely to give the motion characteristics you are looking for.
Nice idea, probably not practical. |
|
| |
Waiting for an explanation of "lightning". |
|
| |
ooh, I want a large altar / coffee table!! |
|
| |
A map display at the bottom lets you figure out, through occasional breaks in the clouds, just what's getting destroyed. |
|
| |
Can we get lightning by electrically charging and
insulating the top and by having a fluid solution that
only conducts electricity when the molecules are
aligned just so? |
|
| |
You see, when someone mentions Hurricane coffee table, I
immediately imagine a coffee table where the cups, table,
chairs are screwed down, so that one could enjoy a nice
cup of coffee regardless of an inconvenient breeze in one's
breakfast lounge. |
|
| |
But this idea is far more practical. |
|
| |
//Hurricane coffee table// Are they really running
out of storm names already? We just started naming
storms over here, and it only seems to be
encouraging them. |
|

[+] 5 years later and I've no clue what bad mood I must have been in to mfd it... [removed]. Though, I'm still waiting on how both lightning and hurricane are going to be achieved at the same time. |
|
| |
Tesla coil? But some version of Lord Kelvin's
Thunderstorm would be extra cool, if it could be
powered by the hurricane somehow. |
|
| |
I will agree that the top of this table/box needs a
cooling system, just as much as the base of this box
needs a heating system. |
|
| |
As for lightning, there needs to be a substance added to
the mix that can be ionized, but not TOO easily. An
external voltage gradient could be applied to let
charges accumulate at opposite points inside the box
(the more different pairs of points, the better). After
an appropriate time has passed, switching the polarity
of the two points might result in a flash. |

Methane ? A 9% concentration ? |
