Testing for Acids & Bases
We LOVE experiments in our house so I duly set off in search of litmus paper (also called pH paper). None of the drug stores that I visited had it (actually some didn't even know what I was talking about).
So we dug deeper...
Did you know that Litmus paper is made using chemicals found in purple cabbage?!
So we stopped at our local organic vegetable stand at the Farmer's Market and bought a purple cabbage for $3.00
Daughter chopped up two cabbage leaves.
