I have not tried this one yet.  I believe we will try this and the marble trick Thursday night during The Artistic Biker Live!  Jerry’s Artarama has a tip listed for painting with bubbles.  You make colored soapy water with dish soap, water and food coloring.  Then you blow through a straw to make bubbles and capture them on your page.  When it dries, BUBBLES!  Definitely have to try that one.  If any of you try it, send me pictures!
