While working on a Bubble art idea for a Fruit of the Spirit lesson, I came across www.hellowonderful.com's Bubble Art ideas.

It uses a unique homemade "bubble blower" made out of a recycled plastic bottle and bit of mesh. You dip it into liquid dish soap that's been mixed with water and watercolor paint and it produces MOUNDS of bubbles (not the kind that blow in the wind).  Check out their photos and instructions at https://www.hellowonderful.co/...ubble-art-with-kids/

I took one of their bubble project images and made a quick photoshop sample of how you could make the bubble art then "paint the rush of a mighty wind" into the bubbles using a brush or hands.  You could also fingerpaint the "Pentecost crowd" and disciples into the mural, or cut them out of plain paper, lay them on the canvas, and remove them after all the bubble paint has been applied.

I'd probably change the color palette to be more "Pentecosty/Fire-y"  ---ALTHOUGH, since the Spirit painted with "all the colors of the wind" we could too and the different colors represent all the different "tongues" (languages, kinds of people) of where, how, and to whom God wants us to share the good news.   

Start with Dawn Free & Clear Dish Soap (or any other clear kind) and add water and colored paint to desired mix. A 6:1 water to soap is typical.  The bubble bottle with the mesh produces large heaps of colored bubbles that drop onto the canvas, not the kind that blow in the wind.

My suggestion: Cover your kids with plastic trashbags to "contain" the bubble slurp.
