i remember i studied in my 10th standard, not all metals attract to magnet., metals named nickel, cobalt will attract to magnet and their ores too, why dont other metals attracted to magnets ? i remember their symbols also Ti - Titanium (hardest metal) Fe - Iron Co - Cobalt Ni - Nickel Cu - Copper Gd - Godolinium (dont know of this one so, i improved video quality amd zoomed to see the answer) W - Tungsten (used in bulb filaments) i have a question already mentioned, someone please explain Thank you :)
The "I LOVE YOU" card is clever. Makes me want to go work one out, for birthday cards, or whatever. It would be interesting to see the resultant patterns, if they are apparent (probably not), uncovered. To me, the hearts are obvious on the open card, the lettering, not so much, but building them, they would more likely be. I knew a guy once that had done so much editing on reel to reel tape, using his fingers to wind back to the beginning of sentences, etc. that he became proficient not only at understanding the speech in reverse, but could actually speak normal sentences, recording them, playing them back in reverse, and they were understandable. Three, not that there is anything wrong with it, just that it gets monotonous, maybe get a few versions and change it up with each new toy, or occasionally throughout the video. You asked. I'm not sure I understand the totality of the physics going on in the reverse hourglass. Maybe some attractive or frictional/rotational forces between the beads, keeping them from just passing through the neck, at the total passage diameter. Or more likely, the reverse flow required of the liquid being displaced through the neck, as the primary retardant driver? The geometry of the phenomena makes me guess the latter, especially at the lower separation interface. It looks like more than one, as well. Interesting. The suspended ornaments in the 'liquid' is super clever. Had you not shown that one, I'm not sure I would have come to that conclusion, especially if you had pointed out that they were truly stationary, with no buoyancy driven movement. I can think of some other ways to do that, but not ones where you could chose placement, and have them truly stationary, negating variations on that same theme. Probably people smarter than me on the subject could, though. Using the hydrophilic material so that the index of refraction was near perfect was genius. I wonder how many of those types of illusions were thought up out of the blue, and how many were "lucked into"? When you do studies, you find that MANY materials, chemicals, etc. were the outcome of happy mistakes. I saw acoustic levitation demonstrated quite a while ago. Great implementation for a toy version.
Pity all my Xmas presents are done already :D Got the hovering magnet lamp a couple of years ago to my parents, probably after one of your videos, always a success when visitors come at home :) And yes, I admit I immediately regretted I didn't get it for myself.
Where are you all from 🌍?

i remember their symbols also
Ti - Titanium (hardest metal)
Fe - Iron
Co - Cobalt
Ni - Nickel
Cu - Copper
Gd - Godolinium (dont know of this one so, i improved video quality amd zoomed to see the answer)
W - Tungsten (used in bulb filaments)
i have a question already mentioned, someone please explain
Thank you
:)
Magnets will attract iron, cobalt, nickel and gadolinium.
the music track; Cyberpunk Synthwave - Black Rainbows. very nice track
Truly the magic of science.
We need to understand science and excel in it to sustain
Sustain what. exactly?

Finally a video that's longer than 10 minutes!
"Holiday decor" is very interesting.🙂

Хорошая музыка у роликов.
No need to zoom, in desktop all are visible... 😅
anyway I didn't know about what Gd & W stand for... Fe, Co & Ni attracts to magnet for sure...
background music ⭐️⭐️⭐️⭐️⭐️
