Flash Cooking SystemADVANCED FOR 2018! Boiling water may not be rocket science, but doing it in 100 seconds takes a lot more than rubbing two sticks together. To create the new Flash, we challenged every aspect of our already iconic stove, modeling the combustion and selecting materials to optimize efficiency, speed and precision. The result is our fastest ever stove: a backcountry cooking system that cuts a full minute off our best boil time. Prepare for liftoff.
