First, we need to make our bubble blower.  Place your empty water bottle on your cutting board.  Using your X-Acto knife, carefully cut around the bottle just below where the bottle begins to have straight sides.

Cut a piece of your string bag large enough to cover the open end of your newly cut bottle.

Lay your bottle on top of the string bag.

Use a rubber band to attach the string bag to the bottle.  You now have a homemade bubble blower.

Next we will make the paint.  Pour some bubble liquid into a shallow bowl.  Add food coloring of your choice.  Don't be shy with the food coloring.  The more you add the more vibrant your colors will be.

Stir the liquid to incorporate the color.

Make as many colors as you like.  It is best if you have a blower for each color.  Set out your bowls of color and your paper.

One by one begin blowing colored bubbles onto the paper.

Experiment with the colors, with the distance from the paper, with the size of the bubbles - do whatever you like to create your own unique work of art.
