My favorite posts of Lian's are the projects that have him excited to be learning or doing something new. I actually had two favorites and I can't decide which I like more.
I loved watching his face when he saw the colors and they were so vibrant. I love fizzy projects. They always turn out so well even when they don't work, of course, this one worked out very well.
This was exciting because we not only were able to get it to work right the first time, but we also able to make it work a second time (Solar Powered S'mores ). I have the perfect box in storage and I can't wait to expand on this experiment over the coming summer.
This project is Baking Soda and Vinegar Fireworks. I love doing baking soda and vinegar projects because they explode all over the place. Once I used them to inflate and explode a balloon and I use them all the time to make my volcano erupt.
The reaction happens because the sodium bicarbonate in the baking soda and the acetic acid in the vinegar combine to release carbon dioxide gas in the form of bubbles.
For this project we used food coloring, baking soda and vinegar. We tried to hide the food color so the color only happened when the reaction occurred. A few drops of color in the bottom of the cup and enough soda to cover it. You don't need a lot of vinegar to make it react. It was so cool. It is a fun way to spend the afternoon.
