Oh What Do You Do in the Summertime?

Help! With Dan being gone for the third summer in a row, I am running out of things to keep myself and the kids entertained. Any ideas or suggestions? Keep in mind that parks are out of the question because of the heat and my house has to remain pretty much spotless in case any prospectus buyers come to take a look. Here is what we have been up to during these hot, hot, hot summer days in East Texas:

Visiting the local splash park once a week:

Swimming when we get a chance (there are only private pools here)

Going to the Discovery Science Place

Eating lots and lots of popsicles

Playing with water guns (we need to get bigger ones!)

Playing Will's V-Smile or pbskids.org

Watching movies

Cleaning the house constantly

Trying to make Weston Smile

With Dan not home in the evenings the days seem to drag, cooking food is not as much fun, and I have less structure during the day. If you have any craft ideas, yummy and easy summer kid friendly recipes, or other activity ideas send them my way. How are all of you spending your summer days? And please PRAY that our house sells soon, keeping it clean is driving me insane!
