And even so, he realized that he did not know the breaking tension of this blade, did not even know if it couldbe broken.

These tiny cubes are small enough to hold water without breaking its surface tension, so the sides of the cube can be completely open without the water spilling out, meaning the surface area exposed to the air outside is much bigger.

这些微小的立方体足够小， 可以在不破坏其表面张力的情况下容纳水，因此立方体的侧面可以完全打开而水不会溢出， 这意味着暴露在外面空气中的表面积要大得多。
