Pippin's Question Box

What makes soda fizz?

The fizz in soda is my favorite part of the drink. That fizz comes when soda creators force carbon dioxide, water and other things (flavoring) into the drink at high pressure. So when you open a can or bottle of soda you get the fizz come to the top because all the pressure is realeased. The gas bubbles come free from the liquid coming to the top!

Now most people also enjoy shaking a can or bottle of soda and then opening it, because I know I do! Well when doing this we "input energy."

So basically, when we shake a can of soda we are mixing all the gas at the top with the soda. So once we stop shaking all the bubbles expand and push their way to the top bringing along some soda and they push out all the soda and bubbles, creating the mess.

To avoid the mess people tap the side of the bottle or can so that all the bubbles on the side of will float to the top.

I got my facts from:
