We had a blast making bubble art! We used Crayola Washable Colored Bubbles-Screamin' Green as well as a homemade colored bubble solution. To make the homemade colorful bubbles I added food coloring to a recipe that called for items I already had on hand, which means I used sugar instead of glycerin.
I gave R a piece of plain white paper, and in order to make the art he had to use the paper to "catch" and pop the bubbles. When the bubbles popped it left various designs on the paper. He had so much fun with this. In between the bubble popping he had a huge grin plastered on his face. He came up with new ways to play. He'd say "I'm going to run really fast to catch the bubbles this time" or "I'm going to dance and catch the bubbles." So it was really about the process.
We loved the Crayola bubbles but we didn't care for the homemade. I had him wear just some old shorts in case the food coloring in the homemade bubbles stained his clothes. Turns out we wouldn't have had to worry about it because when they popped they barely left behind any color whatsoever. The Crayola bubbles were much more vibrant and we wound up playing with that the most. I'd like to buy a few of the other colors because I think the combination would make some really pretty artwork. I later realized though, that I should have probably used washable paint instead of food coloring in the ones we made. We might try that next.
The Crayola bubbles are really messy, which was part of the fun. By the end of the bubble blowing we were all covered in green spots and splatters. R would laugh wildly when a bubble would pop in our faces and a splatter of green was left behind. It is completely washable though and came off of our skin and out of our clothes quite easily. These bubbles are perfect when you have the time and opportunity to get messy. It combines bubbles and mess! And art! And silly exercise! What could be more fun for a child?!
*Edited to add- I've since heard that the Crayola Colorful Bubbles do stain. We didn't have that problem, but it's something to watch out for. I would suggest wearing old play clothes you don't mind ruining, just in case. Honestly I would still do this activity, in clothes we didn't care to ruin, because it was that much fun.
