As the title suggests, we built a working mock-up of the rocket mass stove in my kids' sandbox. I have been super keen on building one and learning about them for a while, so one day, having all the parts we needed to do it, with the help of a couple friends we put this together to test if the concept worked using clay chimey flue. It seemed to work really well. Here is the video of that first burn. Enjoy!
Cheers!
