‘Lost in Space': Would Will Robinson’s Magnesium Idea Really Work to Melt Ice?

Netflix’s reimagining of the classic 1960s sci-fi TV show “Lost in Space” sees the Robinson family marooned on a distant alien planet and encountering all kinds of dangerous hazards. In the first episode, the Robinsons confront one such life-threatening space problem when they crash-land on an alien planet and their ship, the Jupiter 2, melts its way into a glacier. Judy (Taylor Russell) dives in, hoping to retrieve a battery from the crash, but it’s so cold that the water quickly freezes, and Judy is trapped in the ice in her space suit.
