I suddenly find myself wondering if I could make carbonated water by mixing citric acid baking soda directly in a 2-liter bottle, and pressurize it by screwing the cap back on quickly. It's probably a really bad idea due to the risk of explosion if you add too much reagent, and also because you'd end up with a bunch of sodium citrate in your carbonated water, which seems like it would be safe to drink but might not taste good.

Please film it. Thanks.

You probably could, but you'd have the taste of citric acid (which is not awful) and baking soda in the water. The Spärkel has the water that activates the reaction in a separate chamber so they don't wind up in your drink. You need to change that water every four or five times you use it.
