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 :
👉🏻 Single Tube Nixie Clock: This minimalist clock uses a standard 5V USB connection and modern electronics to power a single Russian made ИH-14A Nixie tube- here the display shows the time 12:36 flashed in sequence.

👉🏻 CMYK Coasters: physics and psychophysics of four color printing demonstrated with acrylic slides that assemble to reveal Vermeer's "Girl with a Pearl Earring". Cyan, magenta, yellow, and black (key) comprise the elements of the subtractive color model used in most color printing.

👉🏻 Physics toys featured in famous movies and series
1) Drinking Bird Heat Engine: time lapse of 15 minutes into 15 seconds (4 cycles). Cooling by evaporation at the head leads to lower pressure in the top bulb, the dichloromethane fluid rises up the neck making the bird top heavy and the bird tips over dipping its beak and letting the fluid return to the bottom bulb. The time lapse allows a clearer picture of how the fluid rises, shifting the center of mass, and how tipping makes the glass column lift out of the fluid in the bottom allowing the pressure to equalize and letting gravity pull the fluid to return to the base. Process repeats as long as the top stays wet. So much physics in one hypnotic toy!

2) Van de Graaff Generator: this miniature electrostatic generator can create potentials of more than 50,000 volts allowing sparks to jump a few centimeters through dry air. Similar physics to the sparks created when shoes scuff on carpet, a moving rubber dielectric belt carries electrons away from the top sphere leaving it positive charged- as can be seen by the electrostatic repulsion of some Mylar strands. A small battery powered 3V motor drives the belt via the bottom pulley in this unit that costs less than $10 US.

3) Switch Pitch Ball: this spherical assembly changes color by turning inside out when tossed into the air. Advertisements for this toy incorrectly claim air drag is involved in the transformation. The ball is made of multiple components hinged together. In launching the ball from the hand an upward acceleration results in a torque that pivots each component around its center of mass, causing the rotation of these components in an organized way leading to the transformation. Imagine tossing a stick straight up. If the stick is perfectly vertical upon launch it will move straight up- but if it is initially slanted at all it will also begin to rotate upon launch. Similar physics underlies the motion of each component of the ball- shown here in 240 fps slow motion. The Switch Pitch is produced by the makers of the Hoberman Sphere.

4) The Swinging Sticks: a driven coupled chaotic physical pendulum as kinetic art where the placement of the rods' axes of rotation are engineered to exhibit the widest range of interesting motion. Four AA batteries and a simple electromagnetic kicker circuit in the base gives a tiny push to a magnet in the end of the large rod, keeping the system in motion for over a year! Perhaps one of the most famous physics toys out there as it was featured in the movie Iron Man II (sitting on the desk of Pepper Potts).

    what’s your favourite subject in school? any school/college student here?
  • @VenTGM09
    The Trammel of Archimedes also shows the real definition of Sine and Cosine, The X and Y Coordinates of a Circle-Orbiting Point.
  • @abba9265
    I’ll never get tired of your videos!
  • @Jethro.Maloku-le.Rey.Kalsitran
    the tube is working like a coil and by moving in this coil, the magnetic ball induces a variation of current in the tube (dynamo effect) which creates another magnetic field that slows the ball because it's of opposite direction and if I remember well, it works also with aluminium
  • @h7opolo
    the magnet is accelerated due to gravity converting potential energy to kinetic energy that creates a magnetic flux, which, in the presence of a conducting metal, induces a current in the metal causing a magnetic flux opposing the magnet's flux which forces the magnet to reduce its velocity via conservation of energy.

    It was actually 12:26 pm at the time I watched this video 😂so cool
  • @jedithusnbixby2108
    7:52 Lenz law when you move a magnet beside a conductor there is some currents produced in the conductor which is known as eddy currents
  • @kevinb1229
    Oh, this brainteaser is an interesting one! Electromagnetics is quite the curious topic, and it's something that people don't think about very often... but this is a demonstration of one of the laws of electromagnetics, Lenz's Law. The magnet passing through the copper tube creates an electrical current, which in turn creates its own opposing magnetic field and slows the magnet's descent. You say it best - physics is ❤!

    Yo thats Trippy as heck! The number changes but doesnt change... how do you say it XD Wow whoever invented that is in another world or something
  • @formablecaesar9170
    When I watched it I was exactly 10 minutes ahead of the clocks time rip me
