Experiments!

The time finally came to do the experiments!  First the children made predictions of what they thought would happen once the two substances were combined.  The general consensus was it would make the white blue, the blue white, and it would feel gooey.

I spilled the beans and told everyone what was in the jars.  Vinegar and baking soda!  I added the blue color for effect...

We gathered together in groups to examine the results more easily.  I poured the baking soda in first, added the vinegar, and BAM!  Well, not exactly 'bam,' but that was the type of reaction I got.  It was not what anyone predicted!
