All that and a bag of chips

and it costs a lot

Aerogel is not a material, it's a structure

Crisps *

There is no "air" in a bag of chips. They use pure nitrogen gas.

99.9%

You mean the biggest aerogel manufacturer before it was cool - Lays?

Bag of chips 99.999999999999999999999999999999999% air

You mean lays? Only 99% air for 3 euro's

Aerogel is cool... If we ever need to stop a vulcano from erupting, we just need to make a big lid of Aerogel and the lava cant come out. Trust me thats how it works.
