The Boring Company, Musk's tunnel construction firm, claimed to have sold 20,000 of the weapons at $500 each, netting a total of $10m (£7.5m). "Nothing makes your baby more zen than a few gentle puffs of a TBC Flamethrower", Musk tweeted.
The Boring Company-branded flamethrowers are listed on the auction site with prices ranging from $3,000 (£2,200) to $20,000 (£14,900). (Shortly after the sale was announced, the items were dubbed "Not a Flamethrower" in order to circumvent shipping regulations against items called flamethrowers.) On Saturday, the company distributed the first 1,000 of them in LA.
The clever idea behind these flamethrower pick up parties originally stemmed from the fact that shipping these devices proved to be quite hard given the fact that they contained propane.
While it may seem like just fun and games to some, people are already burning things down that should probably be avoided, and using the for-sure flamethrowers in ways that violate the terms of their purchase.

Jan du Plessis, the chairman of BT, said: "The Board is fully supportive of the strategy recently set out by Gavin and his team". Following the news of Mr Patterson's departure, BT's shares jumped 3% initially, before dropping back to trade at about 202p.

Still on a roll, Musk followed up with a suggested application for the flamethrower: lighting BBQs and home fireplaces.
Musk tweeted that the instruction manual drew its inspiration from Dr. Seuss' "Green Eggs and Ham". "Works against hordes of the undead or your money back!"
The billionaire said his company will ship a so-called "ice blaster" before the winter. The funds made through these "hot" sales would be, in turn, used to fund other ventures of The Boring Company.
It's unclear how much a round-trip would cost, but the Boring Company said it will be "comparable to or lower than current public transportation fares".
