If aerogel can suspend a brick, and does not burn or conduct heat, hell make an ashtray out of it. (crap, I'm gonna get nailed for this one)

Aerogel is very porous. It would get filthy instantly and be all but impossible to clean.

I like it. Clever, appropriate and possible. +

It gets dirty? Well, it would make a nice impractical gift. Could you bake it clean?

You could just coat it with a thin layer of resin to make it easy to clean. I likes.

If *hell* makes an ashtray, it just might be HOT.

Does this qualify as an invention? "Make an X out of Y"?
-- phundug, May 24 2006


Surely yes, [phundug], provided that the resulting X is somehow superior to (or more fun than?) the more conventional X made out of Z.

Crap I did not think about wind blowing it away.

Come to recall, I've never seen an ashtray made from spun glass wool.
