Flamethrowers have been a part of warfare since the 1st Century, AD – when the Byzantines used a form of incendiary stream called “Greek Fire” to burn enemy ships where they floated. Nearly 2,000 years later, harnessing the destructive power of fire remained integral to military strategies throughout World Wars I and II, where they saw extensive use in the trenches of the European theater.

Now, Elon Musk, the head of revolutionary businesses like SpaceX and Tesla, is selling his own brand of flamethrower online – and if you live just about anywhere in the United States, it’s perfectly legal to buy one.

Technically, Musk selling flamethrowers branded with his tunneling venture “The Boring Company,” shouldn’t come as any surprise: he told us he’d do it in December when the company began selling hats with the company’s brand emblazoned on the front.

“After [we sell] 50k [Boring Company] hats, we will start selling The Boring Company flamethrower.” Musk tweeted at the time.
