Create an illustration that combines elements of science and art. Depict a hand gracefully inserting a glass test tube into water, creating ripples. Use a minimalist color palette, focusing on soft blues and whites to evoke tranquility. Highlight the interaction between the hand, the test tube, and the water, emphasizing the reflection and refraction of light. Aim for a serene, yet intriguing composition that captures the moment of curiosity and discovery.
