Although titled "Plate Tectonics for Kids," it did a decent job of explaining Plate Tectonics.
The graphics were all right, but the narrator oversimplified a few things. For a children's program, probably OK.
In any event, there was never any talk or image in the clip indicating that tectonic plates are "basically floating on a molten inner core."
Rather, the clip correctly points out that the Earth's Lithosphere (crust - including plates - plus upper part of the Mantle, which can behave elastically in a geological time-frame, i.e., over thousands of years) - rests on the Asthenosphere, which is almost solid, but mechanically weak; which in turn rests on the Outer Core (liquid metal); which in turn rests on the Inner Core (solid metal).
The graphics in the clip (and in elementary school textbooks) frequently use orange and yellow for visual clarity - but that should not be taken to mean that the corresponding regions are molten.

You’re too smart to remember the basics...
What happens when you drop a rock in a glass jar full of water? A hand full of pea gravel?? A rock that just fits into the jar??
I can clearly envision voids and caves or caverns, areas small enough to support btheir openings. But area the size of the Pacific ocean??????? No ... No way...
