Mehndi is like painting on your skin with a special kind of ink. The ink is made from a plant called henna, which is ground into a powder and mixed with water to make a paste. The paste is put into a small cone-shaped tube with a tiny opening at the end, like a pen.
When you squeeze the cone, the paste comes out and you use it to draw designs on your skin. You can draw flowers, animals, patterns, or anything else you like. The designs dry and become dark brown over time as the ink soaks into your skin.
Mehndi is often used for special occasions like weddings and festivals, and is very popular in many cultures around the world. It's a fun way to decorate your body and express yourself creatively!
