These pics are from The Great Red Cabbage Water Experiment!! ;D
First you boil up half a red cabbage until the house reeks of it and the red cabbage looks GROSS then you strain out the cabbage leaves and keep the purple water that remains. Pour the cabbage water into several glasses, an ice cube tray (preferably a clear or whiteish one ) or little bowls. Add various household condiments and try to figure out which are more base and which are more acid. As you add your pantry components the cabbage water will change color from deep purple, to violet, pinks to blues and even, if you add the right thing, completely clear!! The kids loved changing the colors back and forth and had a great time trying to guess which color was going to come up next! Alicia noticed that the color changes were less obvious at my house than at hers and we figured it was likely something to do with our water supply... we have VERY hard water here...! Anyway, fun was had none the less! ; D
We used; Peroxide, alum, baking soda, lemon juice, white wine, cider vinegar, white vinegar and laundry detergent.
Serious Sciencsy Stuff !!
Pretty neat fun!! AND we have a ton of purple water left over so we can do it again and again and again! ;D

I love this! Grrr....should have bought a cabbage while I was out grocery shopping today. Next time, after we got to the milk experiment. Tomorrow is HS day at the zoo, and the boys are taking a dino class and a butterfly class. Should be fun! (And I'm sure you'll be able to read all about it on my blog later!) :-)
