After making the shape you take it and you dip it into a container of bubble solution.
The shape is supposed to come out with multiple bubbles inside of it if it was constructed properly. Then Matthew uses a straw to blow the bubbles into one large bubble.
I wish we had had this when they were little. It was good for many hours of fun. He had to be pried away to do his chores finally.
Be careful don't suck!!!!! That bubble solution will clean you out completely.
All great fun and a good lesson on surface tension.
