- 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.

This video contains :
👉🏻 Ambiguous Object Illusion Mug: circle or a square?
👉🏻 Gyroscopically Stabilized Rail Runner: this toy remains upright on a single wheel as it travels along any thin rail or tightrope.
👉🏻 Fiber Optic Spray Lamp: a vintage fiber optic lamp sold by RadioShack back in the 1980s.
👉🏻 Double Pendulum Chaos: chaotic motion from a simple assembly of two physical pendulums (one attached to the end of the other) for which the energy of the system moves frenetically back and forth between the potential energy of gravity to the kinetic energy of motion.
👉🏻 Chaos as Art: a double pendulum with glow tracer screen.
👉🏻 Chaotic Magnet Pendulum: adding magnetic forces to gravity gives this pendulum chaotic motion- not random, but very sensitive to slight differences in initial launch conditions.
👉🏻 Noon Cannon: a working replica of a historical novelty- a meridian cannon where, upon 12 o’clock noon, the sun’s rays are concentrated through a precisely placed lens igniting a fuse which then discharges a miniature cannon. According to Wikipedia, in the 18th century meridian cannons could be found in European parks where they were fired off daily to indicate noontime to the surrounding townships. In the first video, the noon time shot is captured in slow motion and the rest of the video is time-lapse from 10AM to 3PM where the observant will note that I did not have the cannon pointing due north as it should be (off by about 15 degrees).
👉🏻 Fiber Optic Flower Lamp: found this vintage 1980s fiber optic lamp at a local thrift store- and it still works! The fiber bundle is illuminated by a lamp in the base and the color shifting patterns are generated by a rotating color wheel in between the light source and the fiber optic bundle (as seen in the last seconds of the video). Fun physics at a thrift store price.
👉🏻 Happy/Sad Spheres: one ball bounces the other stops dead. The bouncy ball is made of neoprene rubber and exhibits high elasticity. The "sad" ball is made of polynorbornene and converts almost all kinetic energy into heat and sound- approximating/demonstrating the case of a completely inelastic collision. Polynorborene is used in vehicle bumpers, for soundproofing, vibration damping, and other applications where recoil motion is unwanted. Swipe to see the drop in slow motion.
👉🏻 Crystal Caprice Kinetic Sculpture: mesmerizing transformations of a winter themed clear acrylic version of the Helicone via a specially designed base that provides pulses of rotational energy to drive the kinetic toy.
👉🏻 Precision Doodle Top
👉🏻 PCB Tree: green circuit boards in a 3D tree design with a simple flashing LED circuit. A fun kit to assemble in the holiday spirit.
👉🏻 Asterism in a Box: Swarovski pearls, suspended by nylon lines in a specific spatial orientation, represent seven well known stars in the Northern night sky. The pearls in this sculpture show the actual 3D configuration of the stars that make up the Big Dipper! Only from one particular point of view- that of our sun- do they look like the "dipper", and this sculpture shows what this cluster of stars would look like from other “near by” star systems in our galaxy. Note that large pearl in the bottom right represents the star Dubhe, a blue giant some 326 times brighter than the sun and the farthest of the Dipper stars at 123 lightyears away. The rest of the stars range in distance from 58 to 101 lightyears, as measured from Hipparcos satellite telescope mission data. From artist Caroline Bowen of Hypotenuse Studios.

07:41 did you get the answer of this week quiz ?
The steel ball floats on liquid mercury because liquid mercury is much more dense than steel and any other metal and non-metal. I am from India 🇮🇳❤
I'm from India best videos of urs ur content is best

Answer : Because mercury is denser than steel (specially in liquid state)
You are intelligent
Buoyant Heavy Metal: a ball bearing (solid steel) floats on top of liquid mercury. Given that mercury is almost twice as dense as steel, Archimedes's principle predicts that roughly half the ball bearing will stick out exposed above the liquid surface. Mercury (element Hg) is very toxic - please don't handle it without appropriate hazardous material safety training.
@@physicsfun too late ... at childhood I drink some of it !! I don't know what damage did to my health?
There are a few principles at work here. Density is the reason steel floats on mercury but the second principle is buoyancy. The steel ball floats because the volume of mercury displaced is equal in mass to the steel ball. Archimedes for the win.
Physics is ♥️ ... and so much more.
7:41 - densiteeeeh! _(little pun on this crazy man yelling: "Graviteeeh!")_

The pixels displayed in this video are awesome today 10/5!
The _Noon Cannon_ looked cool.
However. The only problem with it is if you wanted it to go off at 12 noon precisely, each and every day, you'd have to constantly keep adjusting the cannon's magnifying lens due to the Earths movement in comparison to that of the Sun.
I am from Montana and I love to watch your videos they always make me feel happy and the music go's along perfectly with it.
Glad you like them!❤️❤️❤️
The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.
The answer to the quiz is Buoyancy: the property of a liquid that determines whether an object will sink or float in it.
7:45 Buoyancy
Saw an amazing device down at Canterbury Cathedral. A pocket sundial that the Augustine monks used to carry around with them in the middle ages.
I bought a pocket sundial about 55 years ago at a mediaeval fair. No idea what became of it, but it would be useless to me now as it was calibrated for California and I now live in England.
Answer- I don't have exactly explanation but, Mercury is more denser as compare steel and also mercury doesn't make reaction with glass, that cause steel ball was flots on liquid,
Property of Mercury- Surface Tension.

My favorites of this video is "Fiber Optic Spray Lamp" and "Fiber Optic Flower Lamp" 😊
But the most favorite is the *ASTERISM IN A BOX* 💖
Glad you liked it ❤️
Science is not meant to cure us of mystery, but to reinvent and reinvigorate it.

BG music choice is a solid 4/5. Really nice tracks!
Glad you enjoyed
Great video love it ...
Really appreciate you hard work by making this kind of video
❤
So nice of you❤️

5/5, I like the music & I really like the amazing stuff.

Your answer because mercury is more denser than a steel ball.
Mercury's density is 13.5 g/ml and
A steel ball's density is 7.86 grams per
cm^3
I _love_ these! Subscribed! I absolutely _love_ physics! Radioactivity is my favorite branch of physics! ☢️👍
The steel ball is less dense than the mercury (Z = 80) metal, so it floats. Also, mercury has very high surface tension, too. You could do this with a cannonball too, if you had _a lot_ of mercury, and it would float. I wonder how a beryllium (Z = 4) ball would hold up in mercury? I have a small beryllium ball, so I should try it! 👆
Thank you _so_ much for these videos! They're awesome! 👍
You are so kind
Always amazing. ❤️❤️❤️
Thank you so much!!
Glad you enjoyed
i like the double pendulum chaos and chaos as art
Glad you liked it
Where did you get that gyroscope monowheel toy?
Please read video description for details.
I would love to have that canned clock.
Ich würde sagen das der Versuch mit der Stahlkugel und dem Quecksilber daran liegt das erstens Quecksilber eine deutlich höhere Dichte als Stahl hat und zudem eine sehr hohe Oberflächen Spannung aufweisen tut ergo kann man den Behälter schütteln wie ein Weltmeister aber die Stahlkugel wird immer oben Schwimmen.
So BEAUTIFUL Your Video,Every Part to part BRILLIANT
Thank you very much!
Metal liquid keeps the ball afloat.
My simple answer is any way mercury is a metal rather in any state if we place anything on top of anything it will stay there and forget about its state, in this case only
Thanks lovely science experience
Glad❤️
The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.
The density of steel is between 7.75 and 8.05 g/cm3. The density of Mercury is 13.6g g/cm3. Thus mercury is more dense than steel and the steel ball will float.
Aluminium, for reference, would be just 2.7 g/cm3. Hence it is so light. it would also float a lot higher in the mercury too, due to it's lightness.
However.
A ball of tungsten having a density of 19.3 g/cm3 would sink in mercury.
Great video again. Very interesting to watch. Keeps our minds ticking over nicely too 8-))...

Mercury (element Hg) is very toxic - please don't handle it without appropriate hazardous material safety training.
Since density of steel is less than that of mercury that's why it's floating...
Yes!

Like previous its all about density
quizz : either density or surface tension. Google for density of both, if steel is heavier then solution is surface tension.

okay, I'm making a noon cannon and nothing will stop me
Happy Super Month! 👩🏿🦰
el mercurio es mas denso y mas pesado que la bolita de acero
Yes! Mercurio es casi el doble de denso que el acero, el principio de Arquímedes predice que aproximadamente la mitad del cojinete de bolas sobresaldrá expuesto por encima de la superficie líquida.
Physics quiz ans.Steel ball floats on mercury because mercury is dense, which produces more buoyant force thus the steel ball floats.

Answer: density. Mercury is ridiculously dense compared to steel.
Wierd density science side fact, if there was a body of water large enough, saturn would float in it.
Denser than most metals
😲 wowwww

Answer: Mercury has a very high surface tension
Mercury is denser than steel
Yes! Mercury is almost twice as dense as steel, Archimedes's principle predicts that roughly half the ball bearing will stick out exposed above the liquid surface.
Solid steel ball float on liquid mercury because "Density" of liquid mercury is more than that of Steel Ball.
What he said. But I'd have just put density. 😁
Quiz answer, because the density of steel is much lower than the density of mercury, or the density of mercury is much higher than the density of steel

I like physics, but i do not know how to write emoticons (heart, smiles, ...) on CZcams comments. There is no button to activate symbols. :-(
😀
Good luck.
You are so kind
If you use a phone then you can add emojis with the onscreen keyboard, just like when texting. Hope that helps.
Emoticons started from ASCII symbols just like your sideways smiley face... ":-)"
The ASCII equivalent for a heart is "

Glad you enjoyed
Ah finally figured out what the music reminded me of czcams.com/video/96DO4V8qrR0/video.html
Mercury is much dense than the steel ball, it is like putting a plastic beach ball on water.
Rate the background music?
Get rid of the lame music and learn how to talk in order to narrate your videos instead of us having to read everything
