Making aerogel at home is unsurprisingly difficult
by Andrea James from on (#562E8)
Aerogel, the synthetic material made of about 1% microporous silica and 99% air, has extremely low density, extremely low thermal conductivity, and extremely low chances of turning out OK when made in a home lab. It took YouTuber NileRed many months of trial and error.
He says his efforts were inspired by an aerogel video by Versitatium (previously)
