omg you think i’m one-of-a-kind?! 🥰 learn about fingerprints below 👇 🔍The science behind fingerprints: Fingerprints form in the womb when different layers of cells on the fetus’ fingertips collide and form ridges. Because the exact pattern of a fingerprint is determined by factors that can vary between identical twins, like umbilical cord length, blood pressure, position inside the womb, and overall rate of finger growth, they can't have the same fingerprints! Unless you somehow injure a finger, your fingerprints have the same pattern your whole life, despite getting worn down as you age. Wondering about the pattern? Fingertips have three different shapes: loops, arches, and whorls. 🔍Do it yourself! Grab an ink pad, paper, and a flashlight. Carefully press the pad of your finger into the ink, then gently press it onto a piece of paper. Use your flashlight to get a better look - do you have whorls, loops, or arches? #science #kiwico #experiments #sciencebehind #fingerprinting #ide...
