This is a great question!

So, there are a few real world applications I could talk about here. Probably the most significant is for vehicles that use compressed air. There are several models of cars in Europe that use this versus petrol (also known as gasoline). For these types of cars it is very important to test everything so the car not only runs, but doesn't blow up. Think about when you open a soda can. You hear a pop, then bubbles start moving around right? You can taste this too when you put soda in your mouth and feel that fizz. If you were to not open, but shake that can (DISCLAIMER: Never shake a can of soda as it is dangerous) enough it would burst due to the build up and agitation of these bubbles. When you are in a car can you feel it moving and shaking as it moves? Probably yes, right? So it is very important that this shaking in compressed air cars doesn't cause a reaction like Mentos and Cola do when put together.

Another really interesting real world application is your stomach. Now, imagine you drink a can of soda very very quickly. All of these bubbles would be sent to your stomach a lot faster than your body can pop/process them. What do you think would happen? If you guessed your tummy would get really gassy and probably sick, you are right.

Hope this helps! Please let us know if other questions come up.
