Artist [Ariel Schlesinger] has managed to replace an air horn‘s compressed air tank with butane fuel. This hack manages to change the pitch of the horn slightly, as well as making one very noisy flamethrower. While not as impressive as other flamethrowers, this would probably take the cake for most achievable. Currently the site containing the how-to is down, but we would have to recommend not doing this at home anyway. Video after the jump.
