    Hot air cooled, contracted, and created partial vacuum is my guess. Make it hot again and it will unstick, I bet.

    Put the whole thing in a pot of water and start bringing it to a slow simmer. This will warm the air inside, expanding it and breaking the suction. I got my stuck blender jar open this way, taking it out as soon as the first tiny bubble escaped and quickly unscrewing it before it could cool.

    Pick which one to save and which one to sacrifice. Smash the sacrifice with a hammer to free the other, break them both and realize this is just so like you and every single thing you try to do starts with a half baked plan, then goes off the rails and ruins everything until you’ve nothing to do but pick up the pieces.

      I’m the kind of person who reads step 1, does it, and then goes on to read step 2. I’m happy I’m not OP.

    The power of suction is physically limited. That means it either isn’t suction or op is crazy weak. My guess is that the plastic melted (probably not from boiling Temp) or op is strongly exaggerating.

        The pressure acts over the area of contact. For a perfect vacuum it would lead to ~1kN of force. This is the same order of magnitude our muscles produce. If you take into account that the vacuum results from cooling over such a small temperature interval the force can’t be too high.

        It’s delta p and not fraction p. The difference between ambient pressure and inner pressure (at least zero) is always smaller than ambient pressure. Delta p is therefore limited.

      How do you figure suction is very limited? You’ve never tried to pull a suction cup straight off, have you? I’m not talking about when suction cups have bad sealing surfaces and slowly leak to the point of popping off or peeling suction cups off from a corner, I’m talking applying it to a good surface and then yanking it.

      A shoddy 4.5" suction cup from Harbor Freight is rated at 80lbs carrying capacity for glass, which happens to likely be the same material as the dish (corelle), judging form the thinness. The bowl is probably plastic and had weight on it while these were hot and wet after washing. Please, let me know if you can lift an 80lb dumbell from the end with a single hand with ease.

    I also think heating everything up is the smoothest solution. But to offer an alternative, I’d use dental floss to get in between the bowl and plate. If the bowl has slightly rounded edges (I believe it will), it won’t be too hard to get floss in. With the floss you’ll get inevitably some air in… Which will equalise the pressure and break the vacuum.

    As an inferior alternative to floss, fishing line could work for this approach as well.

      I feel like this would cause a mild explosion. Not based on any real science, i just imagine that if it’s stuck that good there’s gonna be a more-than-satisfying pop when those finally separate, lol

      That said, i really like your solution ✨

    Hey, if you’re using the hot bowl trick, make sure you pay attention to it; if you leave it to get hot and forget, it will be even harder to unstick it because the escaping hot air inside will make a partial vacuum when it cools down.

    Hot ass water

    Edit: Clarification: Poor hot ass water on it or dunk it in hot ass water

    Edit 2, electric boogaloo: This is dependent on the material, according to my mother

    Like, a bowl is stuck to a plate?

    Put the bowl in warm water, put ice on the plate. It’ll release within a few minutes
