We did an interesting Science experiment today to test for acidity. It was out of the Usborne book, Science in the Kitchen. My Father's World uses the Usborne Science books and they are really great and easy to use. You almost always have the supplies already because they are common items that you naturally have
around the house. Anyway, today we did a neat test for acidity. First you tear some red
cabbage into small pieces (not necessarily something you always have around the house)
and pour boiling water over it. Then you let it cool for half an hour. Pour it through a
sieve so that you get just the juice and discard the cabbage. Then divide your juice into
several glass containers. Now you are ready to test for acidity. You pour a little bit of
whatever you are testing and if it's acidic the juice will turn pink. If it's not acidic it will
either turn green or not change at all. We tested vinegar, salt, milk, yogurt, lemon juice,
and sugar. It was very interesting and fun!

That is so cool. I did not know that. Now I think I'm going to have to boil some red cabbage and try this out....just for giggles and grins.
Very cool.
that looks like a fun experiment- very colorful! Looks great in the PC prep bowls!!!
