Craft a whimsical and imaginative bubble nail design that evokes feelings of lightheartedness. Imagine translucent spheres gently stacked atop one another, resembling floating suds. Infuse iridescent hues of blues, pinks, and purples to create a mesmerizing shimmer. Incorporate subtle highlights to mimic the reflections found in real bubbles, ensuring they captivate and dazzle with every wave of the hand.
