Could they not be enabled on Steam Workshop as an official mod ? I won ' t even use them just thought this could be an easy way to get them to the people who want them , without including everyone else . <| sep |> The same reason a propane torch doesn ' t explode there ' s no oxygen in the propane tank . Even if the pressure in the pulsejet momentarily exceeded the pressure of the hose and tank , it would only force air a small way into the inlet , which would be blown back out during the next cycle when it intakes fuel . As long as there is a flow of fuel from the propane tank into the jet , there ' s no way for oxygen to make its way into the lines or tank in any significant way . <| sep |> No problem buddy . <| sep |> Comment is very accurate considering what the Lorax actually stood for .
