This is a fun art project for children ages 7 and up. You need paper, crayons (make sure you have a black one), and a paper clip. Take one crayon and rub it over a section of the paper. Use the flat side of the crayon and rub hard. Take another color and do the same to another part of the paper. Cover the entire paper with different colors of crayon. Now, take the black crayon and color over all the other colors until the whole paper is black. With a paper clip or coin, draw a picture by scratching through the black crayon. The other colors will show through where the drawing is scratched.
