Paint that won't wash out.

In the afternoon, the kitten finished her homework and went to the park to play. When it came to a railing, it saw a sign next to it, which said, "Don't touch it until the paint is wet!" " "The kitten is a naughty boy. It thought, "I'm going to touch it and leave a mark on it." With this in mind, it pressed its paws against the railing, leaving a cat paw print. The kitten looked at her work and smiled proudly. The "work" was finished, and the paint was left on the kitten's paw. The kitten found a faucet and wanted to wash the paint off. After washing for a long time, the dirty things on the paws didn't wash off at all. The kitten was anxious and went to find a bar of soap to wipe her hands. But the claws are still not clean. The thought of going home will definitely be criticized by my mother and make my friends laugh, so the kitten can't help crying. Uncle Niu heard the kitten crying and came over and asked, "kitten, what's wrong with you?" "The kitten said," Uncle Niu, I shouldn't be naughty and touch the paint on the railing. As a result, the claws were dirty and could not be washed off. "Boo-hoo ..." Uncle Niu said, "Didn't it say' Please don't touch it until the paint is wet'? Why are you still touching? " The kitten said, "Uncle Niu, I know I was wrong. But this painting ... "Uncle Niu smiled, took something out of the house, poured it into the kitten's hand and helped the kitten wash its paws. Strangely, the paint on the claws was washed away quickly. The kitten said happily, "Uncle Niu, what is this?" ? It's amazing! Soap can't be washed clean, but it can be washed clean. "Uncle Niu said," This is gasoline. Because paint can be dissolved in gasoline, it can be washed clean. " "So, I see. Thank you Uncle Niu! " Said the kitten. The kitten will never touch the paint again.
