This blue block is Aerogel, the lightest solid material on Earth. It is created by removing the liquid from a silica gel and replacing it with gas, creating a foam that is almost entirely air. Despite being lighter than a marshmallow, it is such an incredible insulator that NASA uses it to protect Mars rovers from freezing, and it protects this flower from the intense heat of a Bunsen burner just an inch away. #physics #science #aerogel #frozensmoke #engineering
