Aerogel: one of the coolest materials ever made

Aerogel is the least dense substance ever created, and is used in NASA space suits, and to make the world's lightest ping-pong ball...

Yeah yeah, but is it biodegradable? Decades ago plastic was the "miracle material" and now it composes a great deal of our landfills, hardly any gets recycled, and we have plastic "dead zones" in the ocean because of over manufacturing.

Well, if the material is really Silicon Dioxide (SiO2, or Silica), then you use it every day already.

It's used in so many common items (glass, for example, is fused silica) that it's really not even remarkable anymore. Until new applications like this surface...

I remember a different "lightest substance on earth" which was also developped by NASA, but it wasn't anything like this. It was whitish, lighter than air, very soft, and oddly enough, edible. Even with it's protective plastic wrapping on, it floated in air. Anyone else see that show?

IIRC it dissolves in water, which is one of the reasons why it isn't currently wide spread, I imagine.

Think of all the cool bath toys you'd have otherwise.

Aerogel-ducky, you're the one...

The claim that it supports "400 times its weight in compressive load" doesn't really impress me all that much when the stuff is the "least dense substance ever created."

Still, looks awesome.

Watch it again, its 4000 THOUSAND times.

So is that like FOUR MILLION?!

Oop. I "misremembered" that statistic. Still, even at 4000 times, I stand by the assertion.

Yogi's absolutely right, though. Science needs to kick it up a notch if it wants to hang with Ted.

I have a block of this stuff a friend from HP gave me. It crumbles very easily, and playing with it means you always end up with a little less than you started with. It's cool to shine a laser through it and see the path. I did the blowtorch thing, too, and it works. It also floats on the 'smoke' jut above dry ice if there's enough dry ice in a container like an ice chest.

There's another video somewhere that shows them put a cube of Aerogel in a white hot furnace. He takes it out with a pair of tongs and then picks it up, still glowing bright red. It is such a good insulator and such a bad conductor of heat that it doesn't even feel warm.

It's too bad they don't make more of it so we could all play with it. It is expensive. I can't wait until the patent expires.
