Silica Aerogel Block (2.5cm x 2.5cm x1cm)

Cool

Pictures and description are very misleading! Actual product much smaller. Received item together with a softball bat, items was loose in the box and was nothing but crumbles when I opened the box. Very disappointing.

Be careful when you handle it, it starts to crumble. It comes in a hard to open plastic box with zero documentation. It wasn't as lite as I thought it would be. The picture is misleading, it is much smaller.

I'm very likely to buy some, but I'll do so from a vendor who doesn't bury the actual size of the product down in the description. Rather than a handful as depicted, it is less than a cubic inch.
