This video contains:
1) Neon Plasma Glass: these double walled glass mugs glow orange and blue from the excitation spectrum of neon gas at low pressure. The base contains a high frequency transformer (Tesla coil) that generates high voltage electric fields (but at very low current) from USB rechargeable batteries- which excites the neon to glow, and also serves as a coaster. The inner volume varies in thickness which leads to variations in heat and pressure which in turn produces different excitations (orange and blue) of the neon gas in patterns that dance and dazzle the eye.
2) Eclipse Diamagnetic Sculpture
3) Oscillating Cylinder Steam Engine: a functional “wobbler” type piston steam engine complete with boiler and flywheel. In this design the cylinder and piston both rock back and forth, acting as the valve mechanism to allow the hot steam to enter through a small hole, and then exit on the next stroke out through the tiny exhaust port in the top.
4) Caustic Curve Lamp
5) Magnetic Tractor
6) Chaotic Coupled Rotors
7) Popsicle Stick Bomb: a form of simple tensegrity, the elastic potential energy of the bent sticks is dramatically released under application of a slight concussive force such as an impact with a table top- shown in forward and backward slow motion. Featured here is one of the simplest constructions with 5 flat sticks woven into a spring-loaded configuration held in place by friction and tension induced by the bending of the wood. A nice demonstration of energy conversion- potential to kinetic.
8) Okkake Koma
9) Flywheel Fun: a precision machined kinetic desk toy (with helical motion illusion) that will spin for 30 minutes! A massive cylindrical ring of brass is mounted on quality bearings- the combination of the ring’s large moment of inertia with the low friction contacts allows for amazingly long spin times. The spiral design converts rotational motion to translational motion for a nice visual effect.
10) Thermomotor Carousel
11) Bismuth Maglev Rod: Small magnets are trapped, suspended and floating, within the notch of a rod cast from the diamagnetic metal bismuth. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the small floating magnet supplies the external field.
12) Compliant Mechanical Elephant

04:28 Challenge-1: why does the
larger disk (giraff) move
faster than the smaller
(monkey)?
07:44 Challenge-2
I want you all to answer. Don't worry about getting it right or wrong. Just answer!
The disks spin at the same speed. The giraffe disc has a larger circumference, which is why it goes faster (more distance at each turn)
because the circumference is different
1 the greater circumference causes the disk to move more quickly 2 the magnesium is less dense than the tungsten
C1-A: It's not JUST that the larger disk has more surface area, ...that's definitely part of it, but the reason is HOW it uses that surface area - as more of it comes "in contact" with the top, transferring more kinetic energy due to 'friction & drag'. The smaller one does NOT have the contact needed to keep it's own spin up.
C2-A: Magnesium's Atomic number is just "12" = Atomic mass: 24.305 u - therefore less dense material, ...whereas Tungsten's Atomic number is "74" (Atomic mass of 183.3 u) making it far more dense (heavier).
LOL, ... That popsicle sticks bomb was something I did with my cousins back in 1972 when I was 6 yrs old. My cousin, my age, showed me how to make them and we'd fire them at each other playing war games... (I know, ... it's ALL fun and games until someone loses an eye), ... *: )*
we made them in 1956 when I was six years old.
Clickbait - no sparks between magnets! 🤨
hello respected friend
he do it so that you click his video so that one can relax, one can get knowledge of science, leads to get our fear of science vanishes, the way he presents makes us aware that in everthing there is science, so that one can get knowledge about science concepts, also he do made his thumnail in such a way so that one can imagine beyond their thoughts by seeing the thumnail, so that one can create a innovative mindset, so that one can get curious about those toys, how they are working, how can these concepts used to solve world problems, so that one get their heart fall in love with science rather than scaring, so that you can get interest in engineering, in physics in science and so that one day you create that revolutionery thing for the world, for the humanity, my english vocablury is not that good i will improve it, i hope you got what i am trying to say my friend
i noticed a lot of people saying him why he creates his thumnail that way, atleast he is not wasting your time by making useless videos, the music used in background help you relax and the knowledge he gives in almost 8 minutes we dont get it in our old schools, the way he give challenges increase ones curosity about that
Thank you respected people outthere :)

Because plugging each magnet to a mains line would be somehow dangerous to say the least :P
Jokes aside, yes, I agree with you but I stick to this channel for the quality within.
It also gets me mad when the "wait for it" countdown starts but in the end,nothing truly different happens. It just keeps spinning or keeps bolting or keeps levitating... whoa? Yes, but, I already saw it
You are the real mvp
Challenge 1 answer - I think thats cause of its bigger size means its higher circumference, due to its higher circumference giraff travels more distance on that surface. Its angular velocity increases cause of increased circumference (i mentioned all the points that came in my mind)
Challenge 2 answer - Although it seems weird/cool that small part of cube is equal to thhat big part thats happening because that small part is made up of tungsten metal and bigger one with magnesium and small part has equal mass in less volume as compared to that big part, this is because tungsten(small part) metal has very high density and its atom consists more number of protons and neutrons than that of magnesium(larger part), magnesium metal has very less density as compared to tungsten, so its all game of density and to the one who made a perfect size cube in such a ratio that both have equal masses but in different volume cause of density
i am sorry i may have over ellaborated things, i will improve it
Thank you :)
You are intelligent ❤️
50/50 Cube: a handheld study in material density contrast. This precision machined block is comprised of equal 200g masses of the metals tungsten (W) and magnesium (Mg)- however the volume of magnesium is 11 times that of the very dense tungsten! One must hold and manipulate this simple sculpture for greatest impact. W: 19.25g/cm3 Mg: 1.74g/cm3
"Kunst bin ich, Wissenschaft sind wir"; 4/5
THX for the impressions! ^^
I remember making popsicle stick bombs as a kid (I am in my 60s now)!
4:28 the larger disk has a larger surface area, so it has more friction and rotational force from the top.
8:03 Tungsten(W) is one of the densest metals out there. Which means you need less Tungsten to equal an equivalent weight of a less dense (i.e. lighter) metal such as Magnesium(Mg)
Using almost the same flywheel as the one at 4:46, we machined grooves on the side of it so we could use an airblower to spin it up at high speed. That one lasted more than 30 min. And it was almost impossible to move because of the centrifugal force 😉.
Be warned. It is a really dangerous thing to doo. The speed can really hurt you if your finger gets between the weel and frame when it spins aat high speeds.
These were awesome! Really nice background music too. Super chilled.
Glad you like them!
I love science because it is the only thing that makes sense of this world.
@@physicsfun could not agree more :)
The plasma cups were pretty cool.
They got one thing wrong with the "neon" plasma cups, ionized neon glows bright orange but the cups plasma is blue so it's most likely xenon or argon which both glow blue.
This is like the ultimate museum store.
FYI @0:44 There is no such thing as a "golden magnet" Gold is not magnetic and does not attract or repel magnetic fields. It's gold coated, so it's just for looks and is irrelevant in any other way. It may seem to be a pedantic observation but this is a physics channel so..
Tungsten is evidently 7 times more dense….. which is why it is used in tank rounds
You are intelligent

"WAIT FOR IT (on the Magnetron) Wait for what???
The music starting at 5:55.. What IS it?! It sends me into a complete bliss-out state. 5 out of 5!
track that comes in @5:51 goes hard… def a 5
Because the density of Tungsten is much higher than Magnesium.

The giraffe disk has a greater circumference than the monkey so it travels further each revolution. i know this because i put low profile tyres on my old vdub, and now the speedo's out!
Challenge 1- Giraff vs Monkey disk
Short answer: Gear ratios.
The disks work In the same way that bicycle gears work (or any gear system). The smaller the gear (monkey disk in this case) the less it will rotate compared to the power gear (the spinning top in this case). Where the larger the gear (giraff gear) will rotate more.
Challenge 2- Tungsten vs Magnesium
Short answer: Size dose not equal Mass (Tungsten is heavier)
Tungsten is a very heavy metal and by comparison although the two are different in size, with Tungsten being smaller then the Magnesium, their weight is the same due to the density of the metals.
The popsicle stick bomb I used to make those when I was a kid but we used to throw them and they went like a frisbee they fly like a Frisbee and then they explode when they hit the ground
When they hit "the ground". He says, trying to get us to believe he and his friends never threw them at each other.

I love science because it is the only thing that makes sense of this world.
The most amazing things about these devices and videos is in the question: Why are these things not being explored on a large scale basis to make everything more efficient and possibly solve many issues in our world? I'd say I assume they are, but it sure doesn't seem to be spilling over from whimsy to practical applications very quickly. If at all.
They are often whimsical demonstrations of practical concepts
The military owns(seizes) all the good patents.
The military hasn’t seized any of the ideas from this video, all the physics stuff and engineering shown in these toys are already general knowledge that either just isn’t a very practical use for on a large scale that is more efficient and cheaper than what we already have or we already use some of the ideas from this stuff already. Give an a ample of a patent of something for this video that has been seized by the military or maybe just not go stating things as a fact if you don’t really know exactly what you are talking about

Most of these only work on small scales.
Given two circles spun at some tangent t, the circle with the larger diameter will have a greater angular velocity, this is because given the same rpm, an arbitrary point has to move over a longer distance to arrive at the same relative location. Since distance s is given by the function v*t, for a given same time interval t, the object with the greater velocity will travel a greater distance.
This was the harder question, the easier is the second one, the answer is because they have different densities.
Magnesium is the least dense metal, with a density of about 1.7 grams per cm cubed, whereas tungsten is one of the most dense, with a density of 19.3 grams per cm cubed. You would think then that the magnesium cube would be 10 times larger, but this is not so. In fact this means that one tungsten cube weighs the same as 10 magnesium cubes, if we get the cube root of 10, we get around 2.2, so the magnesium cube would be ~2.2 times bigger than the tungsten one. Given that we know the mass of the cubes, which we round down to 100 we know that the magnesium cube is has dimensions of around 3.7x3.7x3.7cm and the tungsten one around 1.7x1.7x1.7 cm, which indeed follows our guess of around a 2.2 increase in size. EDIT: I meant 2.2 times bigger in dimensions, not in volume, volume is a cube function, so with a 2.2x increase in dimensions the volume would be around 10 times larger indeed.
The giraffe runs faster because it has longer legs. 😁😁😁

50/50 Cube: The magnesium block is bigger because tungsten is much denser, or has higher mass, or weight per volume.
Challenge (50|50 Cube):
because it has a higher density
Why does the plasma arch curve along the glass like a fractal?
Trying to find the path of least resistance which is constantly altering as the charges change across the surface of the glass. It's not fractal just random.
Can you pour a drink in the plasma cup at 0:17 and 6:56 and still get the effect?
Less repetitive generic music, more explanation.
Answer to the cube question: The atomic weights are different…

The atomic mass of Tungsten is 7.5638757457 times higher than Magnesium in it's purest form.
Tungsten - Atomic Mass [u] 183.84, Atomic number 74
Magnesium - Atomic Mass [u] 24.305, Atomic number 12
They made the Tungsten slightly smaller that 1/8 of the cube and the Magnesium slightly bigger than 7/8 to make up for the difference in density to volume ratio.

It seems like that tiny, candle driven steam engine would produce a much, much greater amount of electricity than a solar cell of that same volume,if you powered it with focused solar light ?
Under load, it probably wouldn't turn much at all. It's all speed and no torque
combine enough of them to build up torque
@@troywhite6039 if you were to use gears to create torque, but the time it has enough to turn the generator, it would be moving negligibly slow.
I'm still waiting for it..
Tungsten(W) has a greater density than Magnesium(Mg), that is why they are the same weight but have different volume.
You got it right!

I have the flywheel spinner. I’ve gotten on average 1 hour 30 on a good spin. Rely cool.
I always thought the gyroscope was a brilliant bit of kit, had one when i was about ten. Then later on i had an Euler's disk. Alas i gave that away as a present.
yes its fields but if you see bad you have to imagine 2 dynamic lowest ths is why einsten is better
the candle splitts a time layer the fields start to expand emmit osscuilations and shockwaves, their are simpler formulars to describe this, the relative frozen air has moe static as the freed feidls and stay at theground...
its insane hard to imagien this and keep this in mind

SHUT UP AND TAKE MY MONEY!
The atomic weight of Tungsten is roughly 7.5 times that of Magnesium. there for Tungsten is a denser material and you need less for the same mass.
50/50 block size difference is because of the density of each one tungsten is 10x more dense than magnesium.
