“…The conservation of volume is not limited to bubbles; it also applies to ink droplets, which has sparked debates in the printing industry regarding its impact on L * . Previous researchers [59][60][61][62][63] have studied the breakage of liquid stored between the gap of two horizontally and vertically separated rods. They observed that the volume of the liquid influenced L * ; however, their conclusions were affected by the movement of the contact line 64 during neck collapse.…”

Soap bubbles bring joy to children and can be seen floating in our baths and during dishwashing. We investigate the thinning and breaking of soap bubble necks when subjected to stretching, providing a contrast to the more extensively studied films with open boundaries. Our analysis reveals the difference in the evolution of the profile between film and bubble during the initial non-equilibrium state, known as the roll-off regime. Furthermore, we observe that the scaled profile of the bubble is primarily determined by the ratio V/R3, where V and R represent the air volume and the cap size. The former implies that successive profiles at different times can be mapped onto a master curve by appropriately scaling them with the time until pinch-off occurs, τ. Additionally, the significance of the latter lies in the fact that akin to the insensitivity of films to R during the final pinch-off regime. The process of memory erasure commences earlier in bubbles while maintaining a fixed value of V/R3. Moreover, we discover that the minimum radius which remains independent of both V and pulling speed deviates from the previous prediction of～τ 2/3 for the film. It is important to note that our discussion is limited by the short duration of the roll-off regime, spanning from 10-2 to 10-3 seconds.

This work focuses on investigating the correlation between the evolution of liquid bridges and moisture migration in solid bulk cargo liquefaction. We experimentally investigate the stability of liquid bridges in static and dynamic particles. The liquid-holding capacity of static particles is determined and the formation and fracturing of liquid bridges are related to the particle distribution and particle radius. The spacing of the bottom particles determines the maximum liquid-holding capacity, while the space between the upper particles and the bottom particles determines the fracture position. The particles with larger radii have an increased liquid-holding capacity and a low volumetric moisture content, which confirms that cargo that consists entirely of large particles would be apt to have seepage and would not liquefy. Moisture migration for pendular and funicular liquid bridges during stretching and squeezing is captured. We indicate that the fusion behavior of liquid bridges is an important inducement for moisture migration, and it dramatically decreases the liquid-holding capacity. The findings suggest that cargo with low water content would still cause liquefaction and that the water content should be reduced further for the safe transport of solid bulk cargo.
