Again we are talking about the coffee maker as if it’s the most important part in the quality of your coffee. It’s also how you spot someone pretending to know coffee. Far more important are the beans. After the beans comes your grinder and water quality.

A connaisseur can enjoy every style of coffee making but never bad beans. Industrial type of coffee is mostly on the bad side btw…

These are 50 cm wide half spheres. If you find that comparable to the situation in the picture your appetite must be enormous.

I sadly don’t understand these units and your point is drained in it. The point I want to make is that the “force” of vacuum is limited by the difference of pressures.

You say it changes “drasticly” with area or suction but that is untrue. It changes linearly with area (not drastically) and pressure difference has a maximum. The maximum is defined by the pressure of the vacuum(=0) and the pressure of the ambient air (1 arm). Both are constant so the maximum is constant and actually not that big.

The difference between ambient pressure and inner pressure is always smaller than ambient pressure. Delta p is therefore limited. The force comes from Delta p times contact area which is constant.

I sadly don’t know your units of mass but as I said a perfect vacuum over an area such as the Bowl is as strong as a muscle. The Ravioli will in no world produce a strong vacuum so muscle will win in most cases.

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.

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.

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.

I’m a physicist. If you are an engineer that sounds like a “you” problem.

I always wondered what would happen if you cite an original source of something we consider common sense now. What would nature say if you use conservation of momentum and cite Isaac Newton and the Principia Mathematica.

What if you quote something in latin. For most of science history this was completely normal.

One Word you mentioned showed nicely what you missed here: Plain

Originally it was called an aeroplane. This could be translated with “flat thing in the air”. Which is exactly as ridiculous as your other examples in German. The difference is that Germans don’t mind complicated long words where English does so they just drop the part they don’t like.

If your rigor cortis lasts for more than 2 hours please consolidate a doctor.

Not if you are a toddler. Are you a toddler?

Correct but if the effects are severe we could already say that it’s bad. If they are harmful the effect of currently normal levels is on the milde side.

The toxicity of micro plastics is very minor. To get to the point where it is a problem you need to be exposed to it for a very long time.

I think our asbestos is halogenated organic chemicals like PFAS. They are toxic in every way and we are addicted to their use in food chemistry. Not to eat or anything but to make the packaging look nice.

Because they are indestructible by any natural way their dose in the water supply is ever rising. The cost of health issues is already in the hundred billions.

Micro plastics might be a problem for our children when the dosage in clean water gets to extreme levels.

It’s the Sound they make and a phenomenon called Sand liquification . Basically it means that Vibrations and Air turn Sand in a liquid like state.
