First buy a purple cabbage. Cut it up and put it in a pot of water. Let it boil then simmer for 20 minutes, then cool. Open a window. Your kitchen will smell...um, earthy.
Next, grab assorted concoctions from your cabinet. From L to R ours were: borax, baking soda, lime juice, vinegar, diluted castile soap, and hot sauce.
Add a few tablespoons of your colored cabbage water...
and say COOL!
Thanks to Mom and Kiddo, we had a blast with this science experiment.
I laughed out loud when I read on her blog, "Of course this experiment involves the concept of bases and acids and pHs, but blah, blah we did not bother with concepts!"
Like Kiddo, Mr. Intensity had a grand time of playing, mixing, finding new solutions and colors after the initial experiment.
He liked best the baking soda and vinegar that went "ka-splode!"
