Another day... another step

The rain is out, plumber is in! For the last two days the plumber has been working on the connections for our new kitchen. I could figure out everything except the long tube in the middle of the "kitchen". My husband has a very good explanation for that: "As you can see, we decided to make the center island 12 feet tall (notice the plumbing for the island sink), that way I can throw food at everybody from above."
