All sizes in this video are easily comprehensible. I can grasp a grain of rice. I can grasp a couple and a portion I would eat. A portion my whole family would have for dinner and then a portion a restaurant might use in a busy hour.

With the cube videos it’s mostly “This is a cube of 1m³.” Which is already hard to encounter IRL and have a good concept of. But then it becomes “now all cubes cover the area of Manhattan higher than the Burj Khalifa”. Yeah, those are sizes we know but that are astounding precisely because we cannot really grasp their vastness or tallness.
