GlaDOS is all about science, she's all about research. So where better for GlaDOS to end up than NASA?
Produced by NASA's education & public outreach department, the above video stars the voice of GlaDOS Ellen McLain, basically reprising her role from Portal and Portal 2, to teach students about Nuclear Fusion and Nuclear Fission.
Thanks GlaDOS. You tried to kill me. You tried to obliterate me and grind my bones to dust, but now you are teaching me science and I appreciate that.
