The Secret World of Machines ... https://www.youtube.com/watch?v=sa7o49uOzVI
Perfect Prepper Info (how to make just about anything) and fun to watch as well ... my kids used to love the show (I really miss those days)
TT
The whole series is available right there on Youtube ... they are outstanding
I have been watching some of the “Prepper” series on Nat.Geo.
While I admire their effort, they are really taking a leap of faith thinking that the disaster that they are preparing for will be the one that hits them.
Each type of disaster requires different preps.
There is no one size fits all.
