白雙全在作品中利用行為藝術的方式並以手指作畫筆，以水作顏料在石柱中作畫，一點一滴地把石柱露出的表面弄濕，再以錄像的形式把整個過程記錄下來。
在把石柱弄濕的過程中正是表現時間流逝的情況，觀眾能夠從影像中看到石柱慢慢地由乾燥的表面變成濕潤的表面，時間就像作品中的水一樣慢慢地對事物造成影響，然而這點亦能在歷史中體現出來，歷史就是時間一點一滴地建構出來。
This artwork is expressed in the form of performance art. Using his finger as a brush and water as palette, Pak Sheung Chuen wets the surface of a stone pillar exposed from the water bit by bit while recording the whole process in a video.
As the process of wetting the surface of the stone pillar connotates the passage of time, the audience can see in the video that the surface of the stone pillar gradually changes from a dry surface to a wet one. This sequence resonates with the impact of time on us, which is imperceptible yet significant. The piece also evokes the nature of history - which is shaped by seemingly insignificant historical moments - like the wet surface of the pillar rendered with numerous droplets.
