Great idea making it so you can press at least two at a time. I wish I had seen this video over four years ago. Now we're moving out of our place with a fire place.

Please let us know how these burn with respect to sparks. My grandpa made a much more simple version of these paper briquettes, and when I burned them, it would shoot shreds of burning paper out the top of the chimney. They blew out while they were still in the air, but I was very wary about fire danger if I were to burn the paper when there wasn't snow on the ground. Please let us know.
