World Record Material

Item #001

Aerogel is one of the most impressive materials humans have created. Aerogels are a group of materials in which the liquid part of a gel has been replaced by a gas. The first aerogel was first created because of a bet.

Being the lightest solid material known, aerogels can be up to 99.8% air. It also has the lowest thermal conductivity of any known solid, which means it makes a great insulator.

Due to its high porosity, NASA has even used aerogels to collect interstellar dust particles in outer space.

This 1 oz sample (about 1 heaping handful) of the world's lightest known solid material comes in a glass jar. Commonly called "frozen smoke", it is safe to touch, hydrophobic (repels water), and an outstanding insulator. This is one of our most popular items and essential for any science enthusiast's collection.


Now available in bulk sizes. Please allow a little extra prep time for drums. Reach out for larger inquiries.
