The 2 Things Challenge this week is Water/Art.One of the many stations in the McWane Science Center in Birmingham is the Bubble Room. There you, er . . I mean the kids, can create all sorts of bubbles with a little bit of soap and water. Some are quite artistic, but transient, sort of like performance art. One machine even lets you be inside the bubble. Mason likes to pop them with his nose, and here he waits for a big one with his reflection to settle on his face.
