So, I found a novel new meta material.
I was impregnating some of my sugar powder models with wax, and wanted to test the water resistance of the final result.
So I left some small pieces to sink to the bottom of a glass of water, and forgot about them.
Two days later, the pieces were floating.
Odd, says I.
A quick taste revealed that all the sugar had moved by osmotic pressure to the surrounding water.
I let that dry for a day or two, and now I have a wax structure, nearly identical to the original sugar structure in shape, but the exact inverse in volume.
A very light wax foam.
Now, to figure out what to do with such a thing...

Re: Metamaterial: Wax Foam
Can the foam also be made with something more sturdy than wax, like epoxy or CA?
I will think about possible areas of use for a while.

Re: Metamaterial: Wax Foam
I don't see why you couldn't do the same with CA or epoxy, since the sugar is a fully bonded matrix throughout after it's fully cured, and will be able to be fully removed after infiltration.
I'll have to try that with a small sample object.

Ok, CA may be a fail.
Only penetrated about 1mm into the object, and pretty much fell apart after immersion.
If I had a vacuum pot, I'd try epoxy.
