This video is just mind-bending! I wonder how much time it took to build such a construction and conduct all the measurements so precisely. It dazzled me completely.

the Japanese are an ingenious and heroic race. It is a vast tragedy that Roosevelt, via a plot hatched by the communist cells at State and Treasury, used Japan to backdoor his way into the German/Soviet War. An even greater tragedy that the corrupt Americans later defeated Japan and imposed their feminist-consumerist Kultur. With the result that Japanese women (like White women in America) have virtually ceased all reproductive activity

My kids watched it twice, and when I told them "enough," the little one said "Mommy, you tell me the story of the three little balls!"

It's a winner in my house. Thanks :)

Both too much and not enough. Loved it.

Using hard cover book edges to guide the rolling ball was novel. (At least I think those were thin hard cover books clamped shut). It occurs near the start of the rescue mission.
