I was listening to MPR this morning. The Farmer's Almanac has been released and it's predicting a colder than normal winter. Boo.
Along with the prediction, came a tip that's been used since the 1700's to keep heating costs low. Apparently, you can make it through winter using just one one log. Here's what you do.
Take the log. Run upstairs. Throw it out the window. Retrieve the log. Repeat.
