I experimented with a small secondary burning fire pit using scraps of pails.

I experimented with secondary combustion using the scrap wood from the pail I used in the video "I made a wood stove out of a pail and it turned out to be a rocket stove."

Always a fun to watch your experiments. I agree, there must be walls and depth to hold the flame and gases in place for proper combustion.

Thank you. I enjoy repeating experiments and making unexpected discoveries. Failure is the basis of success.
