Don’t run out of air. Sleep better knowing you have just purchased a disk of air. Yes, you can now buy air as a special material made by NASA, called Aerogel. It’s the world’s lightest solid consisting of up to 99.8% air. It’s a solid. You can hold it. You can hold air.
Aerogel is super strong and can support over 1000X its weight despite 9 out of 10 Amazon reviews saying they broke it just by freaking touching it. 55 dollars down the drain. But you are not sucky, remember? You will not break it.
