1. The puri puffs up because moisture inside turns into steam when fried, pushing outward. If the dough isn't rolled evenly or if one side is slightly weaker, that part expands more under pressure.

    The puri puffs up because moisture inside turns into steam when fried, pushing outward. If the dough isn’t rolled evenly or if one side is slightly weaker, that part expands more under pressure. As a result, one side of the puri becomes thinner than the other. Factors like dough thickness, flour type and oil temperature also influence this uneven expansion. Even scientists continue studying the mechanics of such simple, real-world phenomena.

    Though Earth’s beaches and deserts hold trillions of sand grains, scientists estimate there are far more stars—about 100 billion—in just our galaxy, the Milky Way. This incredible comparison reminds us how vast and mysterious the universe is. It sparks awe and curiosity, encouraging young minds to look beyond Earth and explore space through science and imagination. Such facts ignite a deep interest in astronomy and the study of galaxies beyond our own.

    Nature has created a wide variety of life forms so that each can thrive in different habitats. The unique shapes of leaves or types of insects allow them to adapt, survive and perform specialized roles. This diversity supports food chains, pollination, decomposition and climate balance. The more varied nature is, the more resilient ecosystems become. Biodiversity also helps humans through agriculture, medicine and environmental stability, making it essential for life on Earth.

    Many questions make us curious, such as “Why do seasons change?” or “How does lightning form?” These are everyday wonders that push us to observe, think and explore. Curiosity begins when something puzzles us or seems magical. Science turns that curiosity into learning through questioning, experimenting and discovering answers. This is how children become investigators and science becomes an adventure of exploring the world around us with wonder and logic.

    Dough rises when yeast or baking soda inside it produces carbon dioxide gas. The gas forms tiny bubbles that get trapped in the dough, causing it to expand. Heat, moisture and time help this process. As the gas increases, the dough becomes soft, airy and ready to bake or cook. This rising is a result of fermentation or chemical reactions and shows how living microbes or agents can change materials naturally.
