ఉడికిందొకటి, ఉడకందొకటి, కాలిందొకటి, కాలందొకటి, ఏమిటది?
Explanation
This riddle describes firewood (వక్క), leaves (ఆకు), ash (సున్నం), and smoke (పొగాకు) — the four stages of fire. It's apt because it poetically captures the transformation of matter through combustion: wood burns, leaves ignite, ash remains, and smoke rises, making it a clever way to teach children about fire and natural cycles.
