Mercury videos (i.e., Mercury videos):
1. Mercury tidal lock - double sunrise phenomenon | 1:27: Explicated Mercury's 3:2 spin-orbit resonance and the occasional double sunrises and sunsets on Mercury ☿. Good, longish for the classroom, but worth showing.
2. Mercury's Double Sunrises (Simulation) | 0:39: Mercury's 3:2 spin-orbit resonance occasionally causes double sunrises and sunset on Mercury ☿. Short enough for the classroom.
3. Transit of Mercury Hinode/SOT images | 0:46: Not too exciting, but short enough for the classroom.
4. NASA Scientists' Stunning Discoveries on Planet Mercury | MESSENGER Images Part 1 | 12:43: Too long for the classroom.
