Waxnado
Heat wax and make weather out of it | |
Select a wax with a melting point below the boiling point of water. Heat water and melt the wax in it. Slowly spin the water until a wax tornado shape forms. Keep spinning the water and let it cool until the wax hardens. You now have a cool sculpture of a tornado.

This is potentially an awesome idea. You could use a magnetic stirrer, to avoid having to disturb the waxnado. If I ever find myself with a large quantity of wax, I may try this. |
|
| |
Wouldn't there be a need for instant freezing? A blast of
wart remover or like. Slow temperature drop would have
lumps forming in wax and altering shape. |
|
| |
That is an experiment waiting to be done. |
|
| |
The wax will float on top of the water. When you
spin the water fast enough that the sides ascend
the sides of your vessel via centrifugal force, the
wax will ascend also to the top of that water. You
will have a ring. |
|
| |
But the waxnado could be made using oil instead
of water. It should be possible to find an oil with
the same density as wax. Certainly oil can get
plenty hot, as evidenced by the delicious existence
of French fries. |
|
| |
Another possible thing is to heat a bowl of wax to near the
boiling point, and set the fumes on fire. Without a wick,
the heat from that fire is still enough to keep the top part
of the wax, in the bowl, fuming --which then burns. I know
this is possible because I've seen it done. |

Search "Tornado in a bottle". Many videos. But how to freeze it ? |
|
| |
hmm, if the hot wax were extruded at the bottom of the container from a slowly closing aperture into cold water then there should be some ratio of volume extruded to cooling time needed to solidify the entire structure evenly as it rises in the spinning water. Lavortex Lamp (+) |

No, you won't. The wax will actually move inward, and down the funnel. Anything less dense than the water will tend to move inward; anything more dense will tend to move outward. |
|
| |
If you doubt, take a bowl of water and pour on enough oil to not quite cover the surface, then get it stirring smoothly and swiftly. The oil will head for the centre. |
|
| |
Like the idea but I'm wondering if at the transition point
between liquid and solid it would be prone to just breaking
apart into non-tornatolike pieces. |
|
| |
There's a trick with supercooled ultrapure water, which will stay liquid until it receives a shock. |
|
| |
This sounds like an application for that phenomenon, or something similar. |
|
| |
Perhaps something like a bubble chamber - a sudden change in pressure, equating to an effective change in temperature - triggering solidification. |
|
| |
Or use a photoactivatable epoxy and a very powerful flash-gnu. |
|
| |
No. I don't want to be flashed by unix. |
|
| |
I think the way to do this would be to pour the wax
into very cold swirling water so it hardens
immidiately and is thus strong enough to stand up to
the swirling water. |

Forget about making sculptures, this would make an
amazing candle! |
