Shattered! conventional armor-grade PMMA hit by projectile

[Tekatoarimo]

To all you smart asses out there... this is NOT aerogel... it's PMMA, read the description (Or the video's title FFS) then go watch the related video "What happens when aerogel is hit"

watch?v=cZqfQ9WAUiM&feature=re­lated

It's the exact same experiment except, with aerogel! IKR. Who'd have guessed?

*My* Question: . . .  Is this armor supposed to be reactive/ablative ? ... or ... More like a kevlar vest, to slow and disperse momentum ?? ... or ... Just plain hard and impenatrable ??? The lead developer lists aerogel's brittleness, as a weakness ... a downside, and he talks about modifying/mitigating that ~undesirable~ property.

=?=

why does it look like it's compression from the left side ? the quality is a bit poor. is the bullet compressing it before shatering it ?

Mythbusters needs an Aerogel myth!!!

90-99% of aerogel is air!!!

PMMA is polymethyl methacrylate. AKA plexi-glass, or acrylic. How is this aerogel, which is silicon dioxide + air?

cooool

It looks like glass and stuff but its really just 99.8% air yes air its basically just a structure of hollow nano balls connected to eachother
