Today (10/3) we used our breath to change the pH of water from a neutral to an acid with our carbon dioxide! BTB (a chemical that detects acids and bases) was diluted into water and just simply blowing into it with a straw was all it took to turn the blue solution into a yellow-green color! The sounds of the bubbles we created in the quiet room cracked me up, so I had to take a video!! Science is hilarious (and fun too)!
