Icebergs float because ice is less dense than liquid water. When water freezes, its molecules arrange in a crystalline structure that takes up more space, making ice about 9% less dense than water. This difference in density allows icebergs to stay afloat, with only about 10% of their mass visible above the water and the rest hidden beneath the sur

Tickling is a curious sensation caused by the skin’s sensitivity to light touches or unexpected stimuli. Scientists classify tickling into two types light tickling (knismesis) and deep tickling (gargalesis). Knismesis, like the feeling of an insect crawling on the skin, helps alert us to potential dangers. Gargalesis, the laughter-inducing tickli

Snakes move using powerful muscles and flexible scales on their bodies. Unlike animals with legs, snakes rely on different types of movement, such as slithering, sidewinding, and concertina motion. Their belly scales grip surfaces, allowing them to push against the ground and propel themselves forward. This efficient movement helps snakes navigate

Hiccups occur when the diaphragm, a muscle that helps control breathing, contracts involuntarily. This sudden movement causes the vocal cords to close quickly, producing the characteristic "hic" sound. Hiccups can be triggered by eating too fast, drinking carbonated beverages, swallowing air, or sudden changes in temperature. In most cases, they la
