I made some red cabbage liquid to do some acid base experiments with the boy this afternoon. Cabbage was cheap at the store this week and I felt like it would be a fun quiet day activity. It was. If I was a better blogger there would be pictures of the fun. I'm not. So we will all have to use our imagination. Or go look at the pretty picures on the link I just gave you.
This was so much fun, and so very easy. We would pour some vinegar in first then add some ammonia, then some baking soda, then some more vinegar and lots of foaming and fun. I then let him have a glass of water with baking soda mixed in, a glass of vinegar, and a glass of water and some litmus paper and he had his milk. He discovered that milk will curdle with vinegar and that you can bring the solution back to neutral. Good times.
His only question at the beginning was that this isn't school right? HA! of course not, it is simply fun with acid and bases. heh heh.
