Once upon a time, there was a renowned frog scientist in the world of science. This frog was dedicated to making new discoveries by working day and night in his laboratory. One day, while holding a test tube containing a green liquid, he was working on a new formula. The shelves were filled with bottles of various colored liquids, and the lab lamp illuminated the frog's work.
The frog scientist believed that this new formula could change the world, and therefore, worked with great care. A small amount of the same green liquid was spilled on the laboratory table, demonstrating how delicate the experiment was.
