A nearly smoke­less fire

Popular Science - - BEST OF WHAT’S NEW 2017 -

The smelly, smoky mem­ory a camp­fire leaves on your clothes is the least fun part of an evening oth­er­wise spent eat­ing s’mores. The Bon­fire’s vent­ing sys­tem draws in air through the bot­tom to feed the flames, and also al­lows some to travel in­side the dou­ble walls and ig­nite in jets from holes up top. The re­sult is that this por­ta­ble stain­lesssteel fire pit con­sumes its fuel so ef­fi­ciently that there’s lit­tle ash or eye-sting­ing va­por.
