Thermos cooking In a Ozark Trail Vacuum Insulated Stainless Steel tumbler
My Goal is to make a food heater/ crock pot of of one of these fro my camping/hunting truck. So this is more just a proof of concept. You really should have the spill proof lid if you are going to thermos cook. This is the big Stanley one I have been using. http://amzn.to/2h2qaTM
