Our favourite Kiwi is at it again, crafting a draft furnace in the forest out of only things he can find.
Draft furnaces are used to smelt ore into metals. They are designed suck air through at high speed, so they don’t need bellows to reach high temperatures.
According to the channel’s description, this DIY oven, which used wood instead of charcoal, reached temperatures of about 1 200 degrees Celsius. That’s pretty impressive for something made out of sticks and mud.
Check it out in the video above.
