The Science of Seltzer Water


Soda water may sound like something that was invented in the ‘80s, but we’ve actually been drinking it since the 1600s! People have used different methods to create it over the years, ranging from fermentation to taking carbon dioxide straight from the mines. But do you ever wonder how exactly those bubbles got into your water? 

Soda bubbles form out of a gas called carbon dioxide that is omnipresent in the atmosphere. Carbon dioxide is the gas that creates all the fizziness. The more carbon dioxide you add to water, the more bubbles and tangy taste you get, which is perfect for anyone who loves a twist in their water!

Carbon dioxide doesn’t exactly have a taste on its own, which is why when added to any drink, it creates a sharp, acidic sensation in your mouth. In fact, it forms something called carbonic acid, which in turn creates that crisp, tangy flavor.

The most common way of making your own seltzer is through a seltzer machine, which can be found online or at most department or home goods stores. The only other ingredient you need is the water straight out of your tap! A seltzer machine adds pressure to the water through its wand and creates bubbles as the pressure is released. The tube or wand uses pressure to dissolve and trap the carbon dioxide in your water. This chemical reaction is also used to make beer and soda foamy!

Another way to create bubbles is by dropping the temperature of the water and adding carbon dioxide to it, but you should leave that method to the pros. If you’ve ever wondered why your drinks stay crispier when they’re cold, now you have your answer!

What sounds better than a glass of cold, crisp seltzer to beat the heat while teaching the kids the science of it all? Cheers to a delicious and educational summer!
