作品名稱

水珠 Water Pearls

科學圖說 Scientific introduction

先鋪上黑色玻璃，在瘦果的棉絲上用針筒注射水滴，印證水的內聚力和張力極限。再用噴霧器噴灑，使水氣附著在棉絲上，水珠可持續變大。此時水的折射及反射背景顏色，既像水晶球又像外太空的美麗星球。只要不去碰它，可持續30分鐘不破掉！水的力量真是無法想像！

On top of black glass, water droplets were added to hair-like structures of achenes with a syringe, testing the limits of cohesion and tension. Then, a sprayer was used to attach mist droplets to the hair-like structures, with some of these “water pearls” growing in size. Refraction and reflection created the background colors. The water droplets appear like crystal balls or beautiful orbs. As long as they were not disturbed, they could stay in place for 30 minutes. The strength of water is amazing!
