What is Spray Paint art called and how do you make it?

Ok so i went to Universals Star walk over break and i saw the coolest art being created. There was a man who created scenery pieces by using spray paint and untensiles to create the piece. My question is how do you make these? I would love to create some of my ow, so any information would be great. Thanks.What is Spray Paint art called and how do you make it?
Well,


there are a lot of different forms of spray paint art.


You probably either mean Air Brush,


or Grafitti.


For Airbrush, you need a special paint sprayer,


it attaches to an air compressor,


so it blows the paint out creating a soft look.


And you probably know what grafitti is,


but just on case,


it's a freestyle art with spray paint cans.What is Spray Paint art called and how do you make it?
