What is the love meaning of Rupert's tears?

The meaning of love is: love is indestructible.

Rupert's tears are tadpole-shaped glass tears formed when glass melts and naturally falls into ice water under the action of gravity. The characteristic is that the tear itself is much harder than ordinary glass and can't be broken under the pressure of 8 tons. However, if we grasp its slender tail and apply a little pressure, the whole glass will burst and splash in an instant and be completely shattered.

Extended data:

The principle of Rupert's tears breaking is called "crack propagation", which stems from the internal unbalanced pressure: when molten glass falls into ice water, the glass surface cools rapidly to form a shell, and the glass under the shell is still liquid.

When the glass in the core is also cooled, the condensation volume becomes smaller, and the liquid glass naturally pulls the solid shell to shrink, resulting in great compressive stress on the glass near the surface, and at the same time, the core position is pulled around and subjected to tensile stress.

When the outside is damaged, these residual stresses are released quickly, which makes the cracks spread all over the body and fragmented. According to the observation of high-speed photography technology, the propagation speed of cracks can reach1450m-1900m per second.
