We know you're not going outside today, so how about a '70s disaster flick about deadly L.A. heat to keep you company?

Someone uploaded the whole movie to YouTube in 2013, so it's just waiting there for you. Fun fact: The film stars Bonnie Bedelia, who went on to play Holly McClane — John McClane's wife in the 1988 Christmas classic Die Hard (and its first sequel). Props to the makeup team, who kept all the actors looking miserably hot and glistening:
