I strongly suspect that the video is impressive to people who are not knowledgeable in Geology or physics.
I also suspect that they leave out a great deal of current Geological evidence which contradicts their claims.
I repeat. The ICR is not a reliable source of scientific information because their stated mission is not open scientific inquiry, but to convert people to their religious view.
To do science, one must go out, look at the evidence in nature, and
then determine what happened.
The Creationists aren't doing science when they hold the preconceived notion that the Flood is true, before they ever look at the evidence.
What they do is hold this preconceived notion, gotten from a religious text, then look for evidence to make it look as though this preferred outcome is how it happened.
