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

This is amazing. Bought for my husband as he's always wanted it and it's just so cool. Definitely fragile so don't squeeze, etc . Size was decent.

Very large, high quality chunk of aerogel. I saw that this seller has stellar reviews as compared to the other aerogel sellers, and saw complaints on other sellers where people received small, broken pieces and mostly "dust". I was happy to see he did not disappoint. Sent me a big, nice quality chunk that I now proudly display in my curio cabinet at work. Great product and it came with a cool display jar!

Not as exciting as I thought but still awesome. Worth the $25. Ill put it on my desk

Not much to say it’s very cool I like the size of the pieces I like to have stuff just to look at and this is perfect for that it always is so cool to see and hold

Fun to show my friends and colleagues. Super interesting material. Can't believe how light it is. It's like handling hard styrofoam and it crumbles very unpredictably.

Pieces are a bit smaller than shown in the pic but overall it is what it says it is. My kiddo wanted this so bad and he’s happy with it!

Absolutely amazing. I was hesitant on whether the quality would be good. But im very impressed. Just as strange and cool as I hoped it would be. Good range of large and small peices. Good transparency.

After reading the reviews from others, I was nervous that it would arrive in too small of pieces. I was delighted to find that we received several good sized pieces, maybe around a half dollar size. There isn't really a use for these other than the novelty of having been able to interact with the product that my husband and sons have been wanting to touch and hold. They're space fans and they first learned about this product from leaning about it's use on spacecraft. Fun item to give as a gift for any space lovers.

Muito interessante

Good material

I’m no science expert, but this is really cool stuff! I’m a bit of an oddities collector, which is why I purchased this. No damage from transport and I actually got a bigger piece than was advertised! No issues with this product that I can see - neato!

Coolest stuff ever!!!!!
