Yup, one of the world's most popular actresses and beautiful women is now practically, kinda, sorta, a member of my family. Ms. Johansson, along with her crew and two small dogs (one of which is purple), moved into the Lakewood home/palace in May, before she started shooting scenes around town for "Captain America: The Winter Soldier."
Sure, the movie ruined my commute to downtown Cleveland for a few weeks and would never have been shot here if it weren't for the state tax credit, but I can't complain. My extended family has benefited from her stay in a number of ways.

If you've ever held a Styrofoam cup comfortably in your hand, only to scorch your tongue sipping the piping-hot coffee inside, you know that plastic foam is a really good insulator. It's also lightweight, generally impervious to moisture, relatively cheap, and strong. With all that in its favor, it would take some effort to find a contemporary, high-performance building that doesn't incorporate foam insulation into key parts of its assembly. But a dark side to foam has come into focus over the last decade. To name a few issues, its manufacturing process can be polluting, its global warming impact can be stratospheric, it is laden with toxic flame retardants, and it is highly flammable, even with those chemical additives...
