Yup, that’s a brick. It’s sitting on Aerogel, “frozen smoke,” the world’s lowest-density solid. The stuff is 99.8% air but can support 2,000 times its own weight, and it holds 15 entries in the Guinness Book of Records. Most amazingly, it was first created in 1931 by Dr. Samuel Kistler. -- source link
