Does steam kill weeds?

Does hot steam treatment kill weeds? This channel will follow an experiment that involves hot steam being applied on an area of unwanted vegetation (for this project, this will be mugwort). The project aims to use an off-the-shelf wallpaper steamer so that the average person can treat unwanted vegetation without hurting the environment with toxic chemical options (like herbicide).
Check out my posts and video descriptions for details regarding the experiment!
