Picking up a takeaway coffee is one of life’s joys – but trying to drink from the lid and feeling like nothing is coming out is beyond frustrating.
Thankfully, there is something quick and easy you can do to remedy the situation. But first, why does this happen?
The reason your coffee seems resistant to escape onto your eager tastebuds when you get takeaway is because of the physics happening right inside your coffee cup.
Inside your cup is your delicious coffee, but also a small amount of air. When you put the lid to your mouth, a seal is created that prevents air from getting into the cup. Without any way for air to enter the cup, and replace the space that would be made by the exiting coffee, the pressure inside the cup rises and prevents the coffee from flowing.
To fix it, you need to allow air to enter the cup at the same time as your coffee exits. Coffee cups have been designed with a teeny-tiny hole in the cap for this very purpose but it does a pretty terrible job most of the time. Moreover, coffees like lattes and cappuccinos can block this minuscule air hole with their delectable froth.
This is where your pen comes in (or anything sharp, if you would rather not risk dunking your Biro in coffee).
Using the tip of your pen, push it into the small hole on the top of your coffee cup to make it larger. If your lid is missing this hole, create one and brace yourself for uninhibited coffee enjoyment!
Of course, another way around the problem is to remember your reusable cup!
