This explanation video from IBM Research is terrific. They turned the MRSA antibiotic-resistant staff strain into an engaging story. Someone did a heroic job of resisting the corporate urge to pile on details and technicalities. I particularly like that they left the puppeteering sticks in plain view.
Note the light-handed branding approach, too. They don't pound on & on about IBM selling ninja polymers. It's there, but it's handled factually. (Explanation ≠ commercial!)
The comments on YouTube are interesting. Some gripe about dumbing down the subject, others say it really engaged them. The view counter tells the real tale, though - about 29,000 views within two weeks. Technical, dense explanations don't get that kind of traffic.
Really nice work, on many levels.
