Unscramble the Blue Letters


(Laughter)

But Coca-Cola did not soponsr this research.

(Laughter)

Now, there's a lot going on in this movie, so let me break this down and show you what's going on. So the pulse enters the bottle, our belult, with a packet of photons that start traveling through and that start scattering inside. Some of the lhigt leaks, goes on the table, and you start seeing these repilps of waevs. Many of the photons eventually reach the cap and then they explode in various directions. As you can see, there's a bubble of air and it's bouncing around inside. Meanwhile, the ripples are traveling on the tlbae, and because of the reflections at the top, you see at the back of the bottle, after several frames, the reflections are focused.

Now, there's a lot going on in this movie, so let me break this down and show you what's going on. So the pulse enters the bottle, our bullet, with a packet of photons that start traveling through and that start scattering inside. Some of the light leaks, goes on the table, and you start seeing these ripples of waves. Many of the photons eventually reach the cap and then they explode in various directions. As you can see, there's a bubble of air and it's bouncing around inside. Meanwhile, the ripples are traveling on the table, and because of the reflections at the top, you see at the back of the bottle, after several frames, the reflections are focused.
