Aluminum castings of ant-nests

See how it feels, fire ants?


#3

I wonder if aliens will ever visit earth, pour molten metal alloys into our homes then sell the results on xbay.


#4

No ants were harmed during the… oh, nevermind.


#5

I was interested to see the actual creation process. This vid is from the ebay sellers.

And another from a different source, not for sale apparently.


#6

Actually, fire ants are an invasive species from South America. So the question may be, I wonder if we ever invade an alien planet, will they pour molten metal alloys into our unwanted colonies? It would be hard to hold it against them…

I wonder why aluminum? I recall from high school chemistry it’s a very difficult metal to work with, and tends to burst into flame.


#10

Aluminum’s not that hard to work with. Websearch will find many folks doing aluminum casts, with descriptions/videos of the process. It’s cheap (especially if you’re recycling empties), it has a fairly low melting temperature, it’s light weight, and it doesn’t particularly “tend to burst into flame” under normal circumstances, though there are ways to burn it.


#11

Perhaps you we’re thinking of Ti or something? Aluminum is pretty safe to work with (no molten metal is all that safe, but lots are worse). The only thing I can think of is if you manage to spill water into molten aluminum, you’re going to have a bad time as it produces hydrogen, and molten aluminum is hot enough to ignite hydrogen.

It also ends up with a pretty nice finish that is much more slowly oxidised than iron or copper.

PS I bet you this was the thing that kicked off the idea:

The do the same thing with a concrete and an entire anthill.

As I understand it, exposed aluminum generally oxidizes immediately – but aluminum oxide is (a) transparent, (b) nonporous, and © doesn’t flake off, so effectively it coats itself in a protective layer of corundum and stops oxidizing almost as fast as it started.


#14

I don’t know if 1800 bucks is that cheap. But its all relative


#15

Come to think of it I believe you’re right… Anyone know what the hell is happening when aluminium is exposed to the elements for a long period of time? I’ve noticed that it tends to get cloudy and sometimes gets white deposits of something on the surface.


#16

The oxididized rind is silvery white (or “aluminium colored”) not transparent, but other than that, yes.

Don’t inhale the fumes…


#17

aluminum has a low melting point and is super easy to cast. i’m not sure why you were taught that it tends to burst into flame, it doesn’t…


#18

A better question might start out; if aliens ever accidentally transport us to their alien planet, will they pour molten metal…


#19

Noooooooooo! :frowning:
