Have you ever seen sidewalks and walls decorated with really cool and colorful art? That's what a street artist does! Street artists use different types of paint, spray cans, markers and other tools to create beautiful art on the street. They can make drawings, write messages or even create huge murals.
But street artists can't just put their art anywhere they want. Sometimes they need permission from the owner of the building, or they might get in trouble with the police. Some people might not like street art and think it looks messy, while others think it's super cool and creative.
Street artists also like to make people think and ask questions with their art. They can make art about important issues like the environment, politics, or social justice. Some even use their art to bring attention to things that they care about, like animals or human rights.
So, in short, a street artist is someone who creates colorful and cool art outside, and sometimes uses their art to make people think about important issues.
