Amazing PHYSICS TOYS that will Surprise you!!

Nahrรกno uลพivatelem physicsfun 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.

This video contains :

๐Ÿ‘‰ Parabolic burn mirror

๐Ÿ‘‰ The Civilized Glass: a most elegant version of the famous Pythagorean cup. Functions as a normal glass, but if the glass is filled above the top of the central column a siphoning effect is triggered and all the contents in the glass drains out the bottom through the hollow stem. With this glass moderation is key!

๐Ÿ‘‰ Pixelated Playing Cards: what one sees is all about the lighting with this transparent deck of cards.

๐Ÿ‘‰ Chaotic Pendulum: magnets hidden in the wood base (and in the swinging mass) make this system nonlinear and exhibit chaotic motion- motion that is predictable with physics.

๐Ÿ‘‰ Viscous Flow Mixing Bulb: art from mixing high viscosity fluids. Each LED bulb from EP Designlab captures a unique pattern based on the physics of laminar flow folding resulting from the mixing of viscous fluids- in this case silicone resins. When the resins cure the pattern is captured and frozen in place ready to display as illuminated by an array of 5 LEDs in the standard E26 bulb base. With this process no two bulbs are alike!

๐Ÿ‘‰ 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, andย  black (key) comprise the elements of the subtractive color model used in most color printing.

๐Ÿ‘‰ Stirling Engine: low temperature difference engine turns a fraction of the heat of hot tap water into mechanical motion. For this engine the heat source is the hot tap water, and the heat sink is the room temperature air.

๐Ÿ‘‰ The Levitron: spin stabilized magnetic levitation- will fly for about 3 minutes or more per launch. The spin rate of the magnetic top must be just right for flight, not too fast or too slow. Repost of probably my favorite physics toy of all time.

๐Ÿ‘‰ Aluminum Flip Top and Magnetic Stirrer: dynamic magnetic fields from rotating neodymium magnets in the base induce electric currents to flow in the conducting aluminum of the top. These electric currents then produce an opposite magnetic field of their own via Lenzโ€™s Law.

๐Ÿ‘‰ Refraction Invisibility: when immersed in water the sea creatures disappear on one side of this card. Light rays bend at the boundaries between substances when the refractive index of each is different. This card is made of a silver card stock sandwiched between layers of plastic.

๐Ÿ‘‰ Circularly Polarized Reflecting Scarab: the iridescent jewel scarabs like this one (Chrysina Gloriosa) have a very rare property: they reflect only circularly polarized light! When viewed through a filter that allows only left CP light the metallic greens and gold colors of the beetle are clearly visible, but if viewed through a right CP filter hardly any light gets through and the beetle looks dark brown.

๐Ÿ‘‰ Diffraction Grating Suncatcher: a radial mosaic of thin plastic diffraction gratings produces a starburst of rainbows.

๐Ÿ‘‰ Voltaโ€™s Hailstorm and Electrophorus: electrical forces due to electrostatic charge send foam beads flying in this version of the historic demonstration by physicist Alessandro Volta.

๐Ÿ‘‰ Magnetic Newton's Cradle: the famous collision demonstration reimagined with opposing magnets as the pendulum weights- shown here in two modes of operation. A 1990s desk toy by Fascinations- sadly no longer in production.

๐Ÿ‘‰ Kalliroscope: rheoscopic fluid reveals the convection currents generated by the heat emanating from fingertips. Invented and produced by Paul Matisse in the 1970s, suspended microscopic flat crystals of guanine reflect light and allow visualization of the fluid's motion.

๐Ÿ‘‰ Oil Drop Cascade

๐Ÿ‘‰ Plasma Globe: low pressure noble gasses exhibit glow discharge from high voltage, creating plasma filaments that rise upward due to heating- shown here in slow motion.
