This video contains:

👉🏻 The Alchemist: this sculpture is cast from diamagnetic Bismuth and features a neodymium cube magnet that levitates- trapped between the hands of the ancient scholar. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the cube shaped magnet supplies the field.

👉🏻 Candlelit Infinity Mirror

👉🏻 Diamagnetic Trap Sculpture: a thin disk of pyrolytic graphite hovers and spins in stable equilibrium over a bullseye configuration of magnetic poles. Diamagnetic substances become temporary magnets while immersed in an external magnetic field, and the created diamagnetic field always opposes the external field (in contrast to ferromagnetic substances like iron which attract). Graphite of this type is one of the strongest diamagnets known, and will levitate over a powerful array of neodymium magnets. ✨With sincere appreciation to Tim Rowett for this kind gift.

👉🏻 Dot Animation Card

👉🏻 TrueBalance

👉🏻 Toroflux

👉🏻 Crushmetric Tumbler

👉🏻 Rocking Seagull Kinetic Art

👉🏻 Gallus Lamp

👉🏻 Convection Turbine Tree

👉🏻 Rainbow Twirler

👉🏻 Cylindrical Infinity Candle

👉🏻 Maxwell’s Dynamical Top: one of my favorite demonstrations of the strange properties of rotating bodies- shown here with a 1/2 scale but exacting replica of the famous “Dynamical Top” created and demonstrated by the great physicist James Clerk Maxwell in 1857. When this brass bell shaped top is spinning an interesting stability can occur- push on the pointed stem and the top will push back, forcing the stem against that object, and friction will cause the stem to roll along and trace the edge of the object. Note- magnets are NOT involved here. The key to this design is to make the contact point/tip of the top at its own center of mass, then any frictional force in contact with the stem will produce a torque about the contact point at a right angle to the direction of friction that creates the stabilizing force (students of physics may recognize application of the right hand rule here). This beautiful historical replica is now available from machinist and creator Jim Peever- and as far as I know the only other replicas of this device where made in the 1880’s.

👉🏻 Magneto Aerolux Xmas

👉🏻 From now every toy will levitate

1) The Levitron
2) The Levimoon
3) Diamagnetic Levitation
4) Time's Up
5) Holiday Decor Physics Magic: sparkling ornaments seem to defy gravity within this glass vase table centerpiece. The snowflakes and shiny baubles are immersed in spheres of hydrophilic poly-acrylamide polymer which have an almost identical index of refraction as that of water- thus when submersed they become practically invisible. Note the elasticity of these spheres from the way they bounce, while at the same time they refract their surroundings as a spherical lens. These super absorbent spheres start as hard crystals with a radius of about 1mm and grow to 7mm when immersed in water for an hour or so.
6) Magnetic Suspension Lamp
7) Mini Acoustic Levitator
8) In Defiance of Gravity
9) Bismuth Diamagnetic Trap Levitation

I like the mag-light; practical AND whimsical!

[RobinGarrish]

As requested, love the music - 5. Love the trinkets too! 😃

[PrestfDoom]

I need that floating induction light bulb 😮

[Nelkhael]

Finally a video that's longer than 10 minutes!

[MadCatNobody]

i think if i had that water bottle at work, i would never get any work done because i'd be playing with it all day

[nik-btd]

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.

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.

Why does the thumbnail have clear goobers on the marble tree run?

[SandraCat]

0:10 for those who don’t know, Bismuth is the active ingredient in Pepto Bismol… don’t believe me? Check the label of a Pepto Bismol box or bottle.

[DIONIS]

"Holiday decor" is very interesting.🙂

[rubylouh]

Shame you 'balanced' the six disks by reversing the film of you picking it up from the desk! 😊 Would love to try this myself. Thanks for showing these.

[samarthFI]

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
:)

[samarthFI]

We need to understand science and excel in it to sustain

[programaths]

The plumb line is the easiest t explain while being the most unsettling/uncanny.

[Blckwlf]

Iron will attract a magnet,
Ti - titanium
Fe - iron
Co - cobalt
Ni - nickel
Cu - copper
Gd - gadolinium
W - tungsten

[prophetofducks]

titanium (Ti) iron (Fe) cobalt (Co) nickel (Ni) Copper (Cu) Tadollnium (Gd) Tungsten (W)

[bobair]

Fe, Co and Ni all are attracted to magnets.

[arnab_blue]

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...

[missbilbybadinage]

6:50 I made one of these in high school (13 years old) & made the top 10% in my state.

[flclutch]

I still come back to listen to that often.
