Aerogel | The Lightest Materials on Earth, NASA-Inspired "Frozen Smoke" (Chunks, High Purity, Silica-based)

Received more than expected. Lighter than styrofoam. Very interesting item and a great gift for someone who has everything.

I've wanted to see Aerogel for about 20 years, and I finally pulled the trigger on this after watching a video with a friend. When I received it, both of our minds were totally blown. Incredibly trippy material and super fun. Worth every penny for just the experience alone.Rub a small piece into your hands (far away from your face to prevent inhalation) and pour water into your hands. The water will act like Mercury, due to the hydrophobicity. Then wash your hands.HOWEVER... Be careful handing it to people for them to observe without placing it into their palm directly... Two people shattered my large samples into pieces with minimal grip force between two fingers, not knowing what it was.

I got this to use & integrate into some custom jewelry. There's multiple pieces in the collection that are large enough to use in my design. It's exactly as it was described and should work out well for what I'm making. Good purchase.

Really awesome gift for my nephew. Amount and size as described.

Kids in my class thought this was the coolest thing ever.

I ordered this as a birthday gift for a friend. She absolutely loved it.

Fascinating material .

Really cool just for the party trick of it all. Makes a solid gift for your science nerd friends.
