I just asked deepseek and told it I turned it around poured liquid into the hole
That's an excellent and creative thought! However, physics and practicality get in the way. Here’s why that solution, while clever, ultimately doesn't work:
### 1. The Air Pressure Problem (The Biggest Issue)
When you try to pour liquid into the hole (now on top), you are also trapping the air inside the cup. For the liquid to enter, the air inside needs to escape. Because the only opening is the one you're pouring into, the trapped air creates pressure that pushes back against the liquid, making it extremely difficult to pour anything in without it splashing back out. You'd essentially be trying to fill a sealed container with only one small hole—it's a very slow, messy, and inefficient process.
### 2. The Drinking Problem
Even if you managed to get some liquid inside, you now have a new challenge:
* The hole is likely too large to create a seal with your lips, making it difficult to sip without spilling.
* To drink from it, you'd have to tip the cup, but as soon as you do, the liquid would rush toward the new "top" (the original sealed base), making it almost impossible to reach with your mouth.
### 3. The Messy Reality
The entire process would be incredibly messy. You'd be fighting gravity, air pressure, and the design of the cup itself, likely resulting in more liquid on you and the table than in your mouth.
**In short:** While turning it upside down is a logical idea, the cup's fundamental design—a single hole and an otherwise sealed vessel—makes it **non-functional for holding or drinking liquid** regardless of its orientation. It confirms the original answer: it's an ornamental piece, not a cup.
