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.

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.

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 resulRead more
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.
