The Nat Geo show “I Didn’t Know That” shows us an amazing new invention. A Concrete Pop Up Tent! Here’s how it works – a folded up canvas tent arrives infused with concrete mix, much like the way plaster casts begin as powdery gauze. Installers saturate the fabric and inflate the tent – and less than 24 hours later it is a solid structure that can keep people safe from the elements and other hazards. The invention will help communities afflicted by natural disasters with added emergency storage, and in some cases, shelter.
Very cool. For more viral videos, follow @BrianBalthazar on twitter!
