凝固高速運動液體的攝影方法，一般可達2萬分之1秒。液體由甘油、牛奶、酒精和普通水製成，並在液體中加入食用色素增色。由電磁閥控制的滴管，把液體滴落在一塊放有少量酒精的黑色壓克力板上，由於滴落的液體與酒精表面張力相差很大，落下的液體與壓克力板發生一系列碰撞後，產生了像多層皇冠一樣的奇妙景象。碰撞過程非常短暫，產生的各種奇妙瞬間，一般無法用肉眼觀察，是名符其實的轉眼即逝，彷彿進入如夢如幻的童話世界。

Liquid high-speed photography methods were used. With these methods, shutter speed can reach 1/20,000 seconds. Liquids included glycerin, milk, alcohol and water, with added food coloring. A pipette with solenoid valve allowed for the controlled release of liquid drops onto a black acrylic board to which a small amount of alcohol was applied. Due to the large differences in surface tension between the liquid and the alcohol, the liquid hitting the acrylic board resulted in a series of impact reactions, producing this intriguing image of a multi-layered crown. This process is so quick that it cannot be observed with the naked eye. Through this image we are transported into a fairytale world.
