Making Mealtime Meaningful: Discover how we're giving back with the 12T Cares program →

If you are on a plane, you are probably not thinking too much about the drinks you are ordering. After all, this is our time to unwind.

The friendly skies are certainly far friendlier when you have a drink in hand, of course. That is all well and good but did you know that there is one drink order that is sure to slow everything down for the rest of your flight?

This is because things do not work in the same manner that they do on the ground. The physics are totally different, which is something that the average person does not always take the time to consider.

The airplane’s cabin will stay at the pressure of 8,000 feet above sea level. Obviously, this is not as much as we would feel when we reach 30,000 feet. However, it is far more than you’d feel on the ground. So what does this have to do with our drink orders?

The pressure will cause a sizable amount of foam when the drinks are being poured. This is not ideal and it will affect your drink order.

Those who need to sweeten up their drink with sodas are the ones who are causing everyone else’s drink order to take much longer. In fact, there is one soda that causes more problems than all of the others: Diet Coke.

If you choose to chase your liquor with a soda, you are actually annoying your flight attendant and anyone else on your flight that has asked for an adult beverage.

“I literally have to sit and wait for but bubbles to fall before I continue pouring,” said a flight attendant. They shared these thoughts with the blog These Gold Wings. “Pouring a [Diet Coke] is one of the biggest slow downs on the bar service.” This makes sense now that it has been explained but we swear we had no idea!

Please forgive us, flight attendants. We know better now and we are going to do everything in our power to make sure that this does not happen again in the future. Watch the video below:
