I never saw her use an entire can of Crisco but I saw her use a Crisco can with "who knows what" in there. And as we all know, it doesn't have to be Crisco per-se. There are other brands as well that can be utilized.
I've been told this lasts for 45 days. I've been told it lasts for 45 hours and I would imagine that it's closer to the latter. But,
- in a pinch
- a hurricane
- a tornado
- a black-out
- you name it
it would be a great item to have! Just be sure to store some string as well.
Thank you to the Resilient Family for their simple instructions!
