    OMG, her answer to "why can't I pass my hand through a solid object?" is absolutely wrong! Nucleus has absolutely nothing to do with it! It is all electro-static force: the electrons in the atoms zip so fast that they form a "cloud" around the nuclei. And since these clouds are made of electrons they have negative electric charge, and similar charges repel. Thus, the electron clouds around the atoms of your hand and a table start repelling each other when you get them close enough. Also your hand can't "exchange electrons" with the table - when atoms "exchange" electrons that is how molecules are formed. And you do not form new molecules each time you touch the table.

That means there is no way to pass trough the object. However if you're a charged ion without electrons at all (eg alpha particle) and the solid material is sufficiently thin, than it's absolutely possible to pass right through (Rutherfords gold foil experiment showed that).

    Despite her passionate approach to teaching, a number of her answers have rather significant scientifically errors (her explanation as to why objects don't pass through each other and the mechanics of a typical lava lamp are entirely wrong). Regrettably, camps in education tend to boil down to passion "or" expertise (I use quotes as the camps present a false dichotomy). Many teachers and professors lean to the other side of that dichotomy, emphasizing accuracy without passion. Neither, on its own, is very effective, and I suspect the very existence of that dichotomy creates a sort of feedback loop. Those that focus on accuracy find themselves having to un-teach a lot of errors that had been taught by a "fun teacher," while those that focus on enthusiasm find themselves having to re-teach students how to enjoy learning. The truly great teachers are the ones who find harmony between both methods.

    I don't want to rain on the parade for everyone who's enjoying the video, but that analogy for why objects don't pass through other solid objects didn't seem correct to me. I may be misunderstanding her explanation but I'm pretty sure the nucleus isn't coming in contact with other nuclei. They are not only incredibly small compared to the electron cloud surrounding it. But a positively charged nucleus would repel another positively charged nucleus, no contact possible there without an insane amount of energy. I could be wrong, and there could be a better way to explain it, I'm open to being corrected.

    In terms of touching something, you would be able to get as close as you can to anything else. I think it would have been better if she explained how states of matter and energy relate. Like how it's easier to push your hand through air compared to water because of the speed a molecule is moving at. You could put your hand through a solid object if you gave it enough energy to move its dense mass but then it would probably no longer be a solid (and would also be a ton of energy). Her explanation makes sense but it feels very incomplete and may have just been cut down by the editing team.

    No you’re right her explanation is just wrong. If you’re at the point where 2 atomic nuclei are coming close to each other, this implies the electron densities of the atoms have overlapped, ie formed a chemical bond. Not what happens when you touch something. When you touch something ur feeling the Inter-electron repulsions. Nothing to do with the nuclei.

    The term chemicals adds a subjectively negative meaning to substances so that people don't have to study chemistry to understand: that stuff is dangerous, unpredictable, and thus bad for me.

    It's a bit more complicated as the atom is still neutral. AFAIK the full answer lies in quantum mechanics as electrons can not be in the same place and same quantum state. So if you push the electron clouds of two atoms together, some of the electrons would need to jump to higher energy states.

What she described with the nuclei smacking together would imply you've achieved a fusion reaction every time you touch something.

    I know that the Pauli exclusion principle is physics and not chemistry, but fundamentally, it is the reason why solids are solid. If you want to dumb it down for a mass audience, she could have said the electrons repel each other, as it at least would kinda be close. The thing about nuclei being dense was so inaccurate. I learned a basic version of the exclusion principle in high school physics. For a chemist to be that wrong is rather sad.

    The "not being able to pass your hand through a solid object" I thought was more due to electromagnetic repulsion (more of a physics question at that point). Loved the electron passing as gloves analogy bit, though.

  • @ronozoh

    The reason why we can't pass through each other is not the "incredibly dense nucleus of atoms" it's the strength of the repulsion of the electromagnetic field of electrons, primarily.

    These are not the same lava lamps of my childhood. These were just wax in some liquid that was right on the edge of wax's density, so that when it was molten, it rose, and when it began to cool, it sank. The light at the bottom heated and melted it.

    I was baffled by her explanation even though she's obviously dumbing it down for the laymen, AFAIK it's mostly the electrons which are repelling each other and maintaining bonds with other atoms, protons have barely anything to do with why solids can't pass through each other, but I'm no expert.

You have to have quantum tunneling on a macroscopic scale to actually do that. The question is so absurd it doesn't really have a concrete answer at least without a butt ton of math

    Another way older lava lamps worked was with fluid and semi solid wax! When the wax was solid, it was denser than the fluid and would sink, but when the whole thing was heated by a lightbulb, the liquid wax could float and be moved around by the hot liquid. Different kinds of lava lamps!
