Unveiling the Mystery: What are "I Know What You Did Last Summer" Drink Cups?
The "I Know What You Did Last Summer" drink cups, often referred to as "IKWYDLS" cups, are a line of insulated tumblers that have taken the internet by storm. These cups, designed by the popular TikTok creator @drewbrows, are not just ordinary drinkware; they are interactive puzzles that reveal a chilling message when a hot beverage is poured into them.
Each cup features a seemingly innocuous design, with a summer-themed scene on one side and a mysterious phrase on the other. However, when a hot drink is added, the heat causes the cup to "sweat," and the condensation reveals a hidden message: "I Know What You Did Last Summer." This eerie revelation is a nod to the classic horror film of the same name, adding a thrilling element to the simple act of enjoying a warm beverage.

How Do "IKWYDLS" Cups Work?
The secret behind the "IKWYDLS" cups lies in a clever use of thermochromic ink. This type of ink changes color when exposed to heat, making it an ideal tool for creating interactive designs. When a hot drink is poured into the cup, the heat activates the ink, causing the hidden message to appear as the cup "sweats."
This process is not only fascinating from a scientific perspective but also adds an element of surprise and intrigue to the drinking experience. It's no wonder that these cups have become a viral sensation, with people all over the world sharing their reactions to the reveal on social media.
