Did you know you can make your own carbonated water without dry ice? It’s so easy. All you have to do is mix water, juice, or any other drink, and add equal portions of baking soda and citric acid. We mixed it with Tang a few months ago and it was tasty. It changes the flavor of the water a wee bit, so you don’t want to add too much. Experiment until you find a good consistency. Apparently this is how everybody did it back in the 50’s. It’s a lost art, I guess.
In this video we mixed 1/2 teaspoon of each to the cylinder. We got the idea from Steven Spangler’s Big Bag Of Science.
