Such educational fun going around our Sandwich Generation family. Last week's volcano fun led to more research, including a visit to Magical Childhood, which led to this fun project. My senior mom enjoyed watching us at work as my grandson and I poured a box of baking soda into a long roasting pan. We took white vinegar, added various shades of food color to the vinegar, then used medicine droppers to dribble the vinegar in various designs in the baking soda. What fun to see the fizzing and fuzzing as the vinegar landed in the baking soda.
Then my grandson put straws in the baking soda, added a bit of extra baking soda inside the straws, then dribbled more vinegar into the straws. This made for more fun fizzing up.
It was a fun way to see a chemical process at work and a fun addition to our studies of volcanoes, rocks, and the world under our feet. It was also a great way to spend the afternoon with my senior mom and grandson. That's definitely one of the sweet joys of the Sandwich Generation, don't you think?

P.S. Thank you so much for your comments. I appreciate them very much and read each one. I also do my best to reply to them all but, as you can imagine, there are times (many times, lately :) ) when caregiving needs do not allow for that. Thank you for your patience and your sweet comments.

Amara and I have had great fun with colored vinegar and baking soda. We did ours on white paper plates and she was disappointed that we had no way to shellac them or something so that she could hang her art. Got any good ideas on that one?
