The video cleverly packages complex material science into a bite-sized spectacle, though it prioritizes the "wow" factor over the material's long-standing practical limitations. It is a masterclass in making structural vacancy look like magic to the uninitiated.

π± The solid is about 99% air π€―. #aerogel #shortsAdded:
This solid block you see is about 99% air and it's one of the lightest solids on Earth. It's called Aerogel and it's even used by NASA in space missions.
Aerogel is an extremely good insulator and can withstand very high temperatures and it's so light that it's often called solid smoke. Just a small sample of it costs around $25, but it's extremely fragile. Just pressing it too hard might crush it into powder. I won't ask you to subscribe, but thanks if you do.
