1st Commercial summary:
A boy is about to shoot at basketball, suddenly, his stomach rumbles loudly, after some events, cracks appear in the ground while the boy is holding onto the ball with a fearful expression on his face. Soon, the rumbling stops, but the basket breaks before the boy can shoot. After the ad, he shoots and scores.
Another boy is sitting at lunch, opens his box, but doesn't have any, then his stomach rumbles, and at home, his mom grabs a lunch, runs outside, sees the wreckage, and jumps onto a mail truck to get to the school. When she enters, she throws it to her son, and the rumbling stops.
1st: When the boy has a fearful expression, you can see banners fall.
2nd: In the second school scene during the earthquake, a hard-to-see clock falls off.
2nd: Right when the first scene shifts to the boy's stomach with the earthquake happens, the girl sitting next to him looks at him (Hard-to-see, though)
Both: When the banners fall, and when the mom enters the school, when both earthquakes happen, you can see the screen shake slighty.
Both: Both boys seem to react scared or otherwise to the earthquake.
