I could not believe it. The following idea is from a YouTube video on a channel named @FatherPhi who also has a website. I do not trust anybody on the web anymore. So I tried it myself. And, yes, the same thing happened.

I have a cup where the bottom is open and the top is sealed. What can I do?
ChatGPT said:
Interesting object 🙂
If you have a cup with an open bottom and a sealed top, then as a cup it won’t hold liquid — anything you pour in will just fall out the bottom.
What you can do depends on what you want:
1. If you want to use it as a normal cup
You have two main options:
- Seal the bottom
- Use waterproof epoxy or strong glue.
- Attach a circular plate (plastic, metal, wood) as a base.
- If it’s ceramic, a ceramic repair kit works well.
- Remove or open the top
If the top is just a lid, try removing it.
If it’s permanently sealed, you could carefully cut it open (depending on material).
2. Use it differently (creative options)
Since it’s essentially a tube closed at the top, you could use it as:
- A plant cover (like a small cloche)
- A lamp shade
- A pen holder mounted upside down
- A wind chime body
- A sound resonator (if you’re experimentally inclined 😉)
3. Physics experiment
It could be useful to demonstrate:
- Air pressure (if you temporarily seal the bottom)
- Vacuum effects
- Resonance of air columns
If you tell me:
- What material it’s made of (ceramic, plastic, metal, glass?)
- Whether the top can be opened
- What you’d like to use it for
…I can give you a more precise solution.

You say, I cannot drink out of that cup?
ChatGPT said:
In its current form — no 🙂
If the bottom is open and the top is sealed, there is no way to hold liquid inside it. As soon as you try to pour something in, gravity wins and it runs straight out the bottom.
You could only drink from it if you:
- Seal the bottom, so it can hold liquid.
- Open the top, so you can pour something in from above.
- Or use it in a very unconventional way (e.g., hold it upside down and let liquid flow through — but then it’s not really functioning as a cup).
As described, it’s basically a hollow cylinder closed on one end — not a usable drinking vessel.
Unless… this is a riddle? 😄
You said:
If would not work if I turn it upside down?
ChatGPT said:
Ah 😄 — now we’re getting somewhere.
If you turn it upside down, then:
- The open bottom becomes the top
- The sealed top becomes the bottom
So yes — in that orientation it would function perfectly as a normal cup.
In other words, nothing is wrong with the cup. It was just upside down.
So yes — you absolutely can drink from it. You just need to turn it over 🙂
