Mix a portion of glue, shaving foam, and red food coloring in a cup. Mix well until all of the ingredients are blended. Repeat this step in another cup but use the green food coloring instead.

Cut the paper plate in half.

Paint the inner part using the red fluffy paint then the outer part with green.

For the final detail, cut very small strips of black construction paper and glue them to the red part of your watermelon.

Now your watermelon paper plate craft is ready to be displayed!
