这段视频展示了一块黄油在黑色表面上逐渐融化的过程。开始时，黄油块呈立方体形状，表面光滑。随着时间的推移，黄油开始融化，形成一个黄色的液体池，液体逐渐扩散开来。黄油块的体积逐渐减小，表面变得不平整，最终完全融化成液体。整个过程中，背景始终保持黑色，突出了黄油的颜色和变化。
The video shows a small cube of butter melting on a dark surface. As the butter melts, it spreads out into a thin layer, forming a circular pool of liquid butter around the remaining solid cube. The process is gradual, with the butter slowly losing its shape and becoming more liquid over time. The background remains consistently dark, highlighting the yellow color of the butter as it melts.
A cube of butter is placed on a dark surface, and it begins to melt, spreading out and forming a pool of liquid butter around it. The melting process continues, with the butter cube gradually becoming smaller and the pool of liquid butter expanding further. The butter cube is now significantly reduced in size, and the liquid butter has spread out significantly, covering a larger area of the surface.
