| Setting up the experiment |
 |
| Doing the countdown. |
 |
| The first time was a complete dud with only a few bubbles. |
 |
| This is the second Try: It worked fantastic! |
 |
| It would change from blue, to purple, pink. If you added more citric acid or baking soda it would change color again. So Cool! |
