glassy and spoungy metals..
A2597
Fanboy
in Zocalo v2.0
Interesting (sort of new) material.
this part comes from the pages of (April Issue of Discovery Mag)
Glassy Metal
Harder, stronger, and better- the material of the future.
The wispy metal strip in my hands is 1 inch wide and as thin as aluminum foil.
"Try to tear it," says William Johnson, a materials science professor at Caltech in Pasadena.
I pull- first gentily, but soon with all my might. No go.
"See if you can cut this," suggest Johnson. Handing me a mirror-bright piece of same metal. Its an inch longer, a qquarter inch wide, and as thin as a dime. I bear down with a pair of heavy duty bolt cutters. The metal wont cut. I try again with all my might, Again nothing.
But the most amazing act in this show is yet to come.
"Watch," says Johnson. From a height of about two feet, A steel ball is dropped onto a brick-size chunk of this glassy metal. The ball bounced and bounced, For one minute and 17 seconds. If it would have been any other metal it would have been thump, thump,thump, and then stop.

and someone at HL2.net pointed out,
"It sounds very similar 2 the "alleged" material found at roswell.
I don't know what is more disturbing a conclusion, that Roswell was an ET vehicle crash or that our government has had this stuff since at least 1947...and the public is that far behind."

One thing is sure, when manufacturing this in bigger amounts is possible these will be used in armours layered with very hard ceramics like [url=http://www.exote-armour.com/]Exote[/url]
Looks like my flying car is getting closer to reality... ;)
