She placed the building blocks in front of Su Mo, smiling brightly, "Daddy, you stack the blocks as high as you can."
Su Mo picked up the blocks and started stacking them. Initially, they were all stacked steadily, but when they reached waist height, perhaps because something wasn't placed right underneath, they suddenly collapsed.
"Let me try." Su Motong retrieved the scattered blocks and began stacking them herself.
The blocks piled higher and higher, eventually surpassing the height of Su Mo's stack. Later, she even had to ride on Su Mo's shoulders to continue stacking, and not a single block fell until all were used.
From a structural standpoint, the blocks formed a perfect column.
This was truly perfect in every sense.
Even with the most advanced equipment, even exhausting the current limits of human measurement, observing at units as small as the Planck length, their center of gravity lay perfectly on a straight line, without even an Amie's deviation.
