Can You Solve the Virus Riddle?

This TED-Ed puzzle reminds me of The Andromeda Strain, except the answer isn't fed to us like in the book or movie. You're in a contaminated virus lab, and you have to save the world by figuring out the puzzle. No pressure at all. A long the way, we learn a little bit about patterns and paths, and maybe how not to design a containment facility. (via The Kid Should See This)
