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 enjoy them very much and read each one. I also love the grand ideas so many of you share that help and encourage other readers. Thank you.
