We filled up three different containers with a small amount of water and dish soap.
Then, I added some food coloring. I placed a straw in each container and told the kids to blow into it.
Away we blew! Once the bubbles were over the top we placed paper over them to create bubble prints.
My 19 mth old loved it, but is was difficult to convince him not to drink the liquid.
Thanks to Chasing Cheerios Blog for the idea.
