This video contains:
๐๐ป Ambiguous Object Illusion: repost of this incredible design by Kokichi Sugihara of Meiji University in Japan, the inventor of this illusion and art form. A clever combination of reflection, perspective, and viewing angle produce this striking illusion. My vote for best gift from the G4G13 exchange last year.
๐๐ป Bismuth Diamagnetic Levitation: Element 83 (bismuth) is the most diamagnetic of the elements*. Here a small neodymium magnet is made to float between two 99% pure bismuth 10mm cubes which are held in precise configuration by friction with the parallel walls of the acrylic assembly I made. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the tiny cube magnet supplies the field.
๐๐ป Jansenโs Linkage Walker: a mesmerizing motorized sculpture that features Jansenโs linkage- a unique leg mechanism which converts rotary motion of a crackshaft into smooth walking motion.
๐๐ป Precision Doodle Top: a sharpened pencil lead serves as the point of this wooden spinning top and records the path of contact revealing the intricacies of its precession and motion as friction slows the system down.
๐๐ป Faraday Train Kit: a battery with magnets on both ends and a coil of bare copper are the simple essence of this self propelled craft.
๐๐ป Kinetic Magnetic Wave Wires Kit: explore the surprising ways oscillating kinetic energy is exchanged when repulsive magnetic fields allow masses on springs to interact with each other. Here three weighted springs dance in chaotic motion as they trade kinetic energy.
๐๐ป Tensegrity Mobile Stand: thin cables levitate and support a smartphone at an angle in this high tech precision machined version of the tensegrity concept, invented by Kenneth Snelson and made famous by the architect Buckminster Fuller in 1949. This stand by Kontax Engineering Ltd came as a kit and was a lot of fun to assemble.
๐๐ป Hyperbolic Holes: a straight rod, in this case a pencil, glides through a symmetrical pair of curved holes related to the famous conic section.
๐๐ป Homopolar Motor Type 2: another take on an easy to make minimalist electric motor design: battery, wire, and a magnet attached to the head of a screw which serves as the rotor.
๐๐ป Pharaoh Hollow Mask Illusion: this ceramic lamp features a concave image lighted from the bottom, which appears as a regular convex image via this vintage version of the hollow face illusion.
๐๐ป Hollow Mask Dragon Illusion
๐๐ป Self Propelled Homopolar Motor: cylindrical neodymium magnets supply the static magnetic field for this motor and become the wheels of a very simple vehicle with an AA battery as the energy source.

I was impressed by the presentations of the "magic" of the laws of physics and the meticulous craftsmanship. A most entertaining video. I would still like to know what took ten years, as stated in the headline. Thanks.
-
The most important thing to never stop questioning is YOURSELF.
-
Where's the part that took ten years? Clickbait title. Won't be back. Was it worth it?
-
At last, content that has not wasted my time! Well done!
-
it is clear that we can use many examples from the laws of physics in our lives to get more out of everyday time without harming the environment as we do today...

I always remove the security lock from my axe when I hear the words: It will work forever or eternally

0:56 this thing really works. I built a Bismuth levitator myself 10 years ago. The little magnet just keeps floating for years and years, not touching anything. It doesn't require any power. You can spin the magnet and it will keep spinning for quite a long time, eventually stopping the rotation due to eddy currents and air friction. But it will levitate indefinitely. This does not violate energy conservation and it's not perpetual motion either, just passively stable levitation. Really fascinating physics gadget.

truely wonderful, brings out the kid in us all, thank you
-
Replace the pharaoh with an elf on the shelf. it would freak out the kids thinking they are being watched.
-
The walker looks like it would have obvious real world applications.
-
Almost forgot about this channel. Very entertaining. Love the relaxing background music for this video.
-
The song that comes to mind is "POP goes the weasel!" Love your channel.

That was awesome! I'm just now building a wood lathe I just got. I now know one of the projects I'm going to make. .. Nice work ๐
-
Hi, these are mind blowing!!!!!! Excellent!!!!!
-
the moment when you realize you actually still don't complete understand about magnets
-
Wow! great work! ... "stunning"! ๐
-
I definetly gotta 3d print myself a little desk strandbeast... i don't even have space on my desk...
