- Hi Everyone :)
Welcome back!
I get asked often: "Where did you get all this stuff?" My goal is to share the real magic of science and physics- and to this end I will update here (and in my store) suggestions on where to get some of these toys, kinetic art pieces, and scientific curiosities for yourself.
Purchasing items from the links on these pages will help support my IG page of science and wonder.

👉🏻 PDLC Electric Field Induced Transparency: when a voltage is placed across Polymer-Dispersed Liquid-Crystal film, long skinny molecules align with the electric field allowing light to pass through without scattering- with the field off the molecules thermally randomize and then do scatter the light passing through, producing a milky white translucent appearance.
👉🏻 Deja Vu II: astonishing spring powered kinetic art. Crafted from wood this device has two disks and each has a pattern of curved spokes that can rotate at different rates and direction to produce interesting illusions of motion via moiré interference effects. A ribbon spring drives an ingenious mechanism that uses ratchets (and the rotational momentum of the disks) to create the various visual modes- a half rotation of the disks will result in 20+ minutes of motion. With a full loading of the spring hours of motion will ensue. Another amazing creation by artist and designer William Le.
👉🏻 "Swing Thing": folk craft kinetic art from the 1970s
👉🏻 Dual Axis Sand Pendulum: the kinetic energy trades back and forth between swinging toward the support arm and then swinging perpendicular to that path tracing Lissajous figures in the sand.
👉🏻 Scrap Metal Kinetic Sculpture: a bent spring becomes a coupled harmonic oscillator with two modes of oscillation, one along a horizontal direction and one at an angle.
👉🏻 Moiré Pattern Portal: rotational motion of this moiré pattern creates the animation of radial flowing motion.
👉🏻 "Focal Decoder" Holiday Card: hidden images are revealed through ingenious and intricate Moiré pattern interference.
👉🏻 Moiré Season's Greetings: rotational moiré pattern generation on a Winter Holiday card from MoMA.
👉🏻 Tricolor Plasma Globe and Glow Wand: an engineered mix of low pressure noble gasses exhibit three colors of glow discharge in the plasma filaments that rise upward due to heating.
👉🏻 The Mezmocoin Infinity: precision machined kinetic spinning tops with helical motion illusion- a simple and elegant physics toy for everyday carry.
👉🏻 d6 Cube Tops: symmetry axes are often associated with interesting physics.
👉🏻 Color Flame Birthday Candle Physics: the colored parts of these candle flames are due to excitation of specific chemical elements mixed into the wax.

Some wood types, when wet, can be deformed without breaking, when it dry (wet goes away) the wood recover it's rigid state.
This is not one of them 🙄
That's how we bend popsicle sticks into bracelets.
@@fakenews7266 that's exactly how you could do this.
Correct
Thanks I didn't know but teka wood? Never deform teka wood....the other deform but few ones get to its original state like you mentioned. A wood treat in a kitchen cabinet deform but when dry turn to its original state.
The last one is done by softening the wood in the middle using steam so the wood can be moved further apart just enough to fit the ball through and then the wood is moved back into position and dried again, trapping the ball inside.
You are intelligent
Yes! Put it in some hot water and that will cause the wood to expand just enough that ball pop in.
I think this is the correct method, but there is a guy who makes stuff with lathes, and I saw him cut material out of the cage itself, and then sand it down with the lathe until it became a ball in the cage..
Put compression pressure on the top&bottom side so that the long sides of wood arc (maybe also soak it in water) and then put the golf ball inside and without presser on the ends they return to closed state with ball inside (if it would have been soaked let it dry out)
7:35 the wood was steamed, allowing for a small amount of give before ball placed inside and straighened again will still workable :)
@@fakenews7266 Is it wrong in this case? Because I've literally done it before.
@@fakenews7266 Nope. Not wrong. Right. I've been a woodworker for 25 years and I can tell you this is exactly how it was done.
@@fakenews7266 once again, for the 3rd time. YOU ARE WRONG TROLL. The OP even admits this is how it was done. It's just another version of the "impossible nail" trick
I really really like that deja vu II! As for the golf ball teaser, could it have been done by soaking the woodto soften it, bending a side a bit, inserting the ball, then reshaping it before drying back to solid?
I was going the liquid nitrogen and ball shrinkage way
😂
✔ Only the wood was reshaped.
That's possible but another way is hidden the entrance or constructing the ball like the "trick" or "truco" of put inside a bottle hehehehehe a "boat" or a "ship" or an "elf" del diablo or a "message".
Como me he reido recordando
Using a hydraulic press you could squeeze the ball into the wooden frame, provided you applied enough moist heat (steam) to both the ball and the frame. You'd probably also need to place some support inside the frame on a vertical axis to prevent the wood from breaking.
And I almost forgot- "Physics is the key to our future"!
😂
@@fakenews7266 It was done by softening the wood with hot water so this person wasn't far off. Troll
Aint no one gonna talk about that cool dragon? 0:13
Steam boxes are routinely used by wookworkers to make wood pliable to a certain extent til it cools in whatever shape it has been bent. Thin layers works best so tighter bends can be achieved from laminating them with glue. In this case the 4 slender parts were easily deformed when inserting the ball and reformed before it cooled and dried.
Came here for this comment.
Background music fits well. 5 for me! Thank you. I can't wait till I can afford to buy one of these.
Does anyone else remember those focal decoders being used as copy protection on some computer games in the 80’s? You had to hold up a thing called a lens lok to the screen to try and decode the letters to access the game.
I remember those. As I was watching the video, I said to myself, where have I seen those before? Then I read your comment and it jogged my memory, only to remind myself how old we are. 😂
@@tinak.3022 How old are you guys
@@DrunkMagnus I’m in my 40’s.
@@DrunkMagnus Im 51. We had a ZX Spectrum in the 80’s with the games being sold on audio tape which were easy enough to copy so the software companies tried all sorts of different copy protection from code wheels and charts to physical dongles that had to be plugged in before you could play the game. One of the ideas was this lens lok. On loading a block would appear on the screen which looked like a barcode/QR code, you then had to use the lens to find the access code, usually 2 letters. I have since found out that they only used it on about 12 games as they didn’t take into account different screen sizes and so on which made it impossible for some people to actually use.
@@andycross3783 oh, interesting
Todo está precioso ..👍🏻
1st guess: I think there is a round plug at the bottom glued back in once the ball is inside
2nd guess: steam the wood until soft, compress ends towards center expanding the sides outwards enough to fit the ball, relax wood and let dry.

If the walnut cage stands up on end can you press down and get it to flex/bulge in the middle enough to remove the ball?
Do you need to soak it in salt water for a while first?
My company installed a transit system that passed very close to apartment buildings. People on the transit cars could see into the apartments. The solution was liquid crystal "misting" windows that went opaque in those areas.

0:01 - used e.g. in Japan for shower rooms and hotel windows
6:10 - turning on a corner is the preferred way even for normal dice, try it!
7:35 - wet wood may have been bent outwards?
1:25 This part reminded me of the tilt-a-whirl amusement park ride when the car slows down from losing its momentum but still turns a little then suddenly.....BAM! It swings around full force again! I love that ride! I also love when art and science join together to create beautiful artwork like this.
I don't really get the purpose of the first "toy." A privacy screen? That's really all it seemed to be.
I watched this just for the spinning wood thing, wasn't disappointed.
Does the electro chromatic window work both ways to block the light or only one way. Can you see through it in both directions?
Came someone bring an answer to this question?
Wow! How did they make those slots in the walnut without cutting it?
Wooden part of the puzzle was made in the green then allowed to shrink as it dried.
Super! Thank you very much!
Physics is the key to our future.
I think the last one has something to do with therml expansion
I guess the wood is roughly shaped then heated is a steam bath for about 30-60 mins, when removed the ball is quickly forced into the interior hollow area and the wood allowed to return to shape…then dried sanded and finished.
😂
I've seen PDLC window first time in a TV show called "Beyond 2000" aired sometime in mid '80s. It looked quite similar to the one showed in this video. That was some FOURTY years ago and it is still shown as a novelty.
Fun fact: when I saw it in the TV show, I thought that by 2020 these windows will be readily available in every store selling windows. It is year 2023 now, and I'm sure I'd have trouble locating and buying a window that has this technology built in.
They also use the PDLC windows in Japan for public bathrooms. Its pretty cool!
Del pendulo que pinta o dibuja al moverse me acuerdo de esa idea también. 💡
What is the cause of the dot imperfections in the moire card image?
I need the second one 💗❤️👍👍
The part about the ball and wood not being cut or glued in the process gave me the solution. Once the carving was done, the ball was added by making it from scratch inside the carving.
It was done by softening the wood with hot water and pressing the ball inside. Once dry, the fibers return to their original shape and then the wood is finished
@@Protopious Thought so. Thanks. In truth, that was my first guess. Just figured I'd post my second guess on the off chance it was correct. Plus, I thought it was a 'think outside the box' guess. 😝
Challenge Answer: Decreasing size by making it cooler (as in thermodynamics)?
The wood was soaked in water to a point it was able to bend or open just enough to allow the ball to fit through. When it was dried it returned to its natural shape
The wood was steamed until it was flexible enough to force the ball between the straight pieces.
the wood was soaked over night or longer to give it some flexibility then the golf ball was shoved through and left to dry, i have done it with ball bearings
Yes! Put it in some hot water and that will cause the wood to expand just enough that ball pop in.
I thought that was a translucent monitor. Quit tricking me this early in the morning.
Watch this shit while you’re high makes your night go by

Slowly stretching the wood....using a vice to some extent... Then a swift knock will warp the golf ball(note itself also very flexible) into place
They wet the wood so it's just flexible enough for a golf ball to squeeze through the 2 wood slats...Classic puzzle!
I would love to know how to make the Deja vu ll. It would make an interesting project.
7:34 that's so easy! cut the slots in the block of wood, then use steam bending to widen one slot enough to insert the ball and straighten the legs again while the wood is still soft and pliable. piece of cake.
No, piece of wood. The cake was eaten while waiting for the wood to soften...😋
One thing is "lógica" and other y thing is "logistics".
Una cosa es la "GIMNASIA" Y OTRA COSA ES LA "MAGNESIA".
The ball got in when the cage was warm and wet so it could be bent to allow the insertion of the ball, later straightened by any means, for example by hanging it and attaching a weight to the base and then leaving it dry.

According to how the puzzle question was worded, the puzzle at the end is impossible to make without cutting the wood. How else would you make the wooden cage in the first place?
A coil with a number of turns of 600, in which a magnetic flux of 10 * 3 is generated. Find the self-inductance coefficient of the coil and the induced electromotive force generated
yooooo I've got one for you. With the tesla globe thing (5mins~) you can play a synthesizer square wave into ones with audio input and it will gyrate to the sound wave
Very Nice videos as usual!!!
Can you share the diy for the toy at 2:23

Soak the wood in water until it softens enough to allow the ball to go in. Let it dry (preferably with a vice or weight to get it back in a straight position)

"Physics is the key to our future"....okay, now what?
to get out the golf ball , we simply need to break the wooden thing
La postal roja y verde me acuerdo del contraste tambien lo mismo ruedas opuestas moviendose en un mismo eje.
Got the wood wet and soft, bent it then once the ball was in but it in a jig till it dried.
Regarding the Challenge at the end of the video.
You might be able to get the golf ball in there by wetting the wood and controlling the warp of the wood, to enable the golf ball to fit between the gaps?
I need that second gadget
Please read video description for details.
The puzzle is simple the walnut was Exposed to steam for an extended period of time making the "limbs" temporarily pliable enough for the golf ball to be wdged between and into the center column, then subsequently dried and then stained for finish.
You are intelligent
Yes! Put it in some hot water and that will cause the wood to expand just enough that ball pop in.
you could technically carve a ball and paint it, meaning it could have also been a carved ball so it never needed to be introduced.
Soak the wood in warm water the wood will become soft & then slide ball inside
Excellent
Thank you so much.
Physics is the best. What I love about physics is that as you learn, you don’t really get answers. You just get better questions.
De ese ejemplo de "Newton" hay muchos parecidos y diferentes me acuerdo
De la bolita atrapada en el case de madera me acuerdo eso se usa en las joyerias y otras cosas . El "level" para construir que todo diseño y mueble y piso y counter esten derechos que usan los arbañiles y arquitectos e ingenieros es lo mismo pero un acrilicotransparente o caja cristal o tubito lleno de un liquido fosforescente o fluorescente que tiene una burbuja en el mismo medio cuando esta nivelado.

Now... imagine being able to control your cars window tint level with this. Or, it adjusts automatically during the day to darker when it's sunny to clear at night.
I'm pretty sure there's lcd technology for that.
wood can be bended when it's heated with high humidity, when it's sufficiently bendable, the ball can be inserted and in cooling, the wood retake his original solidity.
De esas ruedas contrapuestas moviendose me acuerdo de la idea 💡
Put the golf ball in liquid nitrogen to shrink it slightly then put in in the wood

How can i make this circle
Made the wood cage, steamed it, then twisted a bit while gently pushing together. Squeeze golf ball into, now larger, opening, clamp till dry to avoid any twisting? ✌️
perhaps using water to deform the wood, or by freezing/heating them both. havent tied either.
I'm guessing moisture was used on the last wood/golf ball puzzle...
Problem solving....soaking in water ....
Somebody loves Sharper Image…
Wood is soaked... golf ball inserted... then dried.
Yes! Put it in some hot water and that will cause the wood to expand just enough that ball pop in.
My guess is that a golf ball became wedged in the nook of a tree's branches, grew around it, and the wood was later carved around the golf ball
Wood was probably steamed and bent to fit the golf ball.
You are intelligent
I carve these but carve the ball inside them as i go. In this case i reckon he has steeped the wood in water, opened enough for the golf ball, then steep it again till wood fibers straighten out again, dry, then sand & finish etc
Del alambre y el movimiento de la luz que dibuja también me acuerdo
the puzzle. shake it baby as hard as you can. the ball inside will deform under the fast motion and will junp out.
Rotation motion tambien me acuerdo
The wood was boiled and bend, and the ball set in. While cooling and drying the wood would go back to it's earlier shape.
Yes! Put it in some hot water and that will cause the wood to expand just enough that ball pop in.
Eso lo había en los 60 en Arecibo PR
The problem is that in order for that walnut wood to have that shape regardless of the ball, it would need to be cut to have been made hollow. 😑
Physica jest kluczem naszej przyszłości
Fizyka opisuje prawdziwą magię wszechświata.
All the comments presume the wooden cage was moistened with water or steam, deformed allowing for the insertion of the ball, reshaped and allowed to dry. What if the cage were made of non-malleable steel? I suggest that what appears to be a golf ball is a clever illusion. It is, in fact, an inflatable ball made of plastic that is designed to resemble the pocked exterior of a golf-ball. The deflated ball is easily placed into the cage. It is inflated to the proper size using an air pump or compressor. In addition to air, the ball is filled with an epoxy that hardens to the proper weight and mass to simulate that of a regulation golf ball. Voilå.
Winter holiday card, do you mean 'Christmas'.
Deja vu II proved to me I did WAY too much LSD and its still affecting me to this day...
Lo de las velas con la llama o flema de colores tengo que recordar pero sí algo así era.
The wood was steam bent to insert the golf ball.

Ironically I love physics but I don't like math I wonder how that would have worked out in college LOL 😂
Sometimes there is no seeming logical connection between the mathematical formula and the visual representation. If you see the visual representation of a fractal and then see the mathematical formula that supposedly translates into that, you would be saying what are these mathematicians smoking.
