A great way to spend the day is to go explore all of the floors at the Children's Musuem of Houston.
We really enjoyed our time at the Children's Museum. Although because of the number or people we almost missed the kidopolis exhibit completely. According to several others that are from the area, there are always that many people at the museum.
After watching the first episode of Nickelodean iCarly, where the main character decides to do a web show, my kids decided that they would like to do a "show". Choosing to share our experiences with others, sounded like a really fun idea.
