Apparently corn syrup makes a thicker layer around the bubble, and the water inside evaporates more slowly, hence longer lasting stronger bubbles. We had loads of fun. If the weather continues this way I'll have to find more outside activities.
I'm thinking of going on a nature hunt and trying a project I found on Pintrest. It's from a wonderful Blog called the Artful Parent. She has some great ideas for art projects with kids. Flower Stained Glass art, it's beautiful and would be a lovely addition to my large kitchen windows. May have to run out and get some contact paper.... hmmmm the possibilities.
