In the last week, you had to have stopped by your local gas station or fast food establishment. You order up your usual, a coffee, slushie, soda, whatever it may be, to go, and you're on your way. But as you head out the door, you notice something on the top of your cup. A few little bubbles are imprinted on the top. Some were pushed in by your barista, while others were left alone. Why? And what exactly are these bubbles on your fountain cup or coffee cup lid?
The first reason behind this is it helps the barista, or waitstaff member keep track of which drink is which. Some lids, especially those found on plastic cups at fast food restaurants, are often used to distinguish diet from regular soda and are even sometimes labeled with "tea" or "other" to indicate which drink is inside.
While on our dive to find out more on what exactly these bubbles mean, we also found out that these lids also have a secret feature! A reset button. You see someone simply pressing down every circular button on top of a soda lid. Then, like magic, you see the same person press on the raised rectangular buttons toward the outside of the lid, which raises the circular buttons back up again, resetting the entire lid!
So there you have it, the easy answer to why your lids have all those fancy buttons. Now, all you need to do is gather your siblings and incessantly annoy them by pressing and resetting the button as fast as you can!
