and if some of you science bastards ice cant beat magma or freeze magma then guess what? it doesn't take ice, ordinary room temperature air will freeze magma/lava. it does not stop the flow because only the surface (air/magma interface) chills solid, the formed solid acts as an insulator to keep the internal flow hot. lava especially often has a lot of gas so it forms a foam froth when cooled which is an excellent thermal insulator
