I was waiting in line today at Tractor Supply with a 50 pound bag of chick feed on my shoulder when I noticed for the first time how they sell disposable hand warmers that last 10 hours. That got me to thinking about how much heat might be captured from something like that with a 5 gallon bucket covering it?

We don't need that level of protection tonight, but it might come in handy if a sudden ice age reared its cold shoulders.

I guess the only way to know would be to test and measure the temperature, but it might work as a last ditch effort to save an outdoor plant if it got more than 10 degrees lower than freezing.
