Hi, I'm here with an important message.

You might think bubbles are cool.

Bubbles are fun, but what if I let you know bubbles can be dangerous,

especially if you don't use the right ones? For example, I was trying to fill my bubble machine, you know, one of those plastic toys that uses a fan to blow tons and tons of magical bubbles.

Well, I ran out of that soapy liquid you use, so I tried bubble gum. Bad move. Now my bubble machines parts are stuck and coated in

pink sludge. See? Dangerous. And the other day I wanted some bubbly water, you know, a carbonated beverage. But all I had was plain water. So I tried putting some bubble bath liquid in it. No, dangerous. That was a one-way ticket to Yuck City with a

pit stop in Aakey Tummyville. But if bubbles in carbonated beverages don't come from soap,

how do they get there? What makes some drinks

sparkly and fizzy anyway? Listener Dot wanted to know this too. Where does the

carbonation and soda come from?

So if we're talking about sodas and other manufactured beverages like this, carbonation is going to be kind of man-made.

Hi, I'm Adam Johnson, I'm a product developer and a food scientist. I studied

chemistry and food science to get here. You force carbon dioxide gas through the

beverage and that results in the bubbles being in your

beverage. If you're doing a natural fermentation like you would see with beer or

wine, kambucha, something like that, that's going to be done via the addition of yeast.

Nitro beverages got pretty popular for a while that uses nitrogen gas instead of carbon dioxide.

And the nitrogen gas is much finer, much smaller size than CO2,

and so you get smaller bubbles

and that gives you more of that richer,

almost velvetyer feel instead of kind of that
