Summer activities for toddlers

We desert dwellers are starting the long stretch of almost unbearable heat, and I've been racking my brain to think of activities for C that will take his mind off the torture of being kept inside and out of the heat.  Here's what I've come up with so far...

- build or buy a water table to play with in the garage in the relatively cool morning hours
- visit the Shark Reef at Mandalay Bay
- have "pool" parties in the tub with toys, bubbles, and bathtub paint
- blow bubbles
- make musical instruments
- color, scribble, and paint
- visit the lion habitat at MGM Grand
- story time at the library
- "paint" with water and old paint brushes and rollers on the garage floor
- make a fort out of the dining room table and chairs and a sheet or two
- make shadows with flashlights
- make a sensory box out of dry beans (anticipating a huge mess!)
- "hide" little objects amid rice in big Ziplock bags or plastic bottles for C to find
- make a quiet book
- collect leaves, etc, on a early-morning walk and help C glue them to paper later
- go for rides in the laundry basket or empty diaper boxes.  then help C give rides to his teddy bear
- practice sorting objects
- sing silly songs with C's name in them
- watch airplanes take off and land at the airport
- 1st baking lesson
- make homemade popsicles
- dance party
- visit the animals at the pet store
- read, read, read
- play dress up
- attend an equestrian show at South Point


Anyone have additional ideas??
