This activity was completely child led.  I was still finishing my breakfast when J started ramming our plastic sensory bin into the back of my chair.  Then he went to the pantry and asked for the baking soda, vinegar, and "colors" (aka food coloring).  So here J's activity.

  • Large plastic bin
  • Baking soda
  • Vinegar
  • Food coloring
  • Squeeze bottles - We used two condiment bottles from our recycling collection.
  • Spoons were added later
I simply covered the bottom of the bin with baking soda and put six drops of food coloring throughout.  Then I filled the squeeze bottles with vinegar.

The set up.
As mentioned, this activity was initiated entirely by J so he helped me set it up.  Then I handed a squeeze bottle filled with vinegar to each of the boys.

K checking out the squeeze bottle.
K is really excited about the baking soda on his fingers.
Starting to put some vinegar in.

J is squeezing in some more vinegar.
The colors are starting to appear.
We also added some spoons to the activity.

Spoons add to the fun.
Stir, stir, stir.
Oh, time to climb in.
It's amazing how baking soda and vinegar can keep kids amused regardless of how many times they try it out.
