A clean white laboratory with a row of transparent test tubes lined up neatly on a pristine white bench. Each test tube contains a tiny, glowing micro-landscape: one holds a dense green jungle with miniature trees and mist, another contains a sandy tropical beach with a tiny ocean wave, the third glows with bubbling red lava and dark volcanic rock, and the fourth is filled with snow-covered pines and soft falling snowflakes. The lab is sterile and modern, softly lit with cool ambient light, contrasting with the vibrant worlds inside the glass tubes. Rendered in a semi-realistic, high-contrast style with crisp edges, surreal detail, and a whimsical, science-fantasy tone.
