This is an easy Christmas craft project for the kids.
You will need:
Clear glass Christmas ball ornaments
several colors of acrylic paint
Remove the top from the ball and squirt in about 1-1/2 tsp. of two colors of acrylic paint.
Put a piece of tape over the open to keep from splattering
And Shake, shake, shake!!!
Place them upside down in a container, an old egg carton works well, to dry. Then replace the top and hang. That's all there is to it!
