Fizzy acid/base reactions never get old, do they?
But, add a pH indicator, like say a viola infusion (see yesterday's Mad Science Make-up Lab for instructions), into the mix...
...and the same old, same old type of fun - which is still fun, becomes mad science fun - which is so much better.
Red cabbage water would work just as well for this, but it wouldn't taste as good - and yes, I said taste, because after all, if you use a powdered sugar free lemonade mix to introduce an acid to the infusion, instead of the normal vinegar...
...you won't just get a color changing volcano, you will get a color changing volcanic lemonade!
But, with a little bit of tinkering...
...to adjust the ratio of baking soda...
...to lemonade, you can come up with a mixture...
...that if not quite good...
...is still good enough to share with the rest of the mad scientists hanging around the lair.

I guess I am going to have to go buy some sugar free lemonade and plant some violas. These experiments are great!
Very, very cool. I am assuming lemonade mix with sugar instead would work, too, right? We are allergic to artificial sweeteners.
The science that can be tasted is the best, isn't it?
Phyllis - Yes, the sugared kind would work, too. It will just add a stickiness factor to the fun :)
Science is our favorite and anything that fizzes or threatens to "explode" is our favorite. All the better if you can tinker with it to make it somewhat tasteable!
I had to come visit when I saw the name of your blog on Phyllis' comments. That totally defines us!! Isn't almost unschooling the greatest? :)
Blessings, Debbie
