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. Buy them on :  on Instagram : video contains :👉 Magnetic Cube: a twisty Rubik’s Cube puzzle made from 27 dice and 208 neodymium magnets. This cube includes the scrambled states and solutions of the original 3x3 Rubik’s Cube but is held together only by magnets!👉 Inverting Valentines Illusion: Love is a matter of perspective in this illusion that depends on viewing angle. 👉 Ambiguous Object model 3👉 Mezmoglobe: precision machined kinetic desk toy with helical motion illusion. Give this metal sphere a spin and the imparted angular momentum (along with precision bearings) allows for sustained rotation. 👉 Tension Integrity Icosahedron: Six brass struts float isolated from each other but held in a stable configuration by a net of 24 connecting cables. This  configuration of three sets of parallel struts forms a Jessen’s icosahedron under tension, and was invented by the famous architect Buckminster Fuller in 1949.👉 Sail Boats by Otagiri: 1970s kinetic art. A delicate balance of torques and a low center of mass lend to this curious motion. Could not resist including the USB fan 😬👉 Paperclip Magnetic Top: the magnetic tipped top attaches to the perimeter of the paperclip- but since the top has much more mass, the paperclip is put into curious motion due to Newton's 3rd law and the top's rotational inertia.👉 Magnetic Tip Spinning Top👉 Swirl Around Top👉 Aerolux Argon Glow Bulb: the filaments glow with the purple light from the emission spectrum of excited argon gas. The background snowflake is coated with green phosphor which is stimulated by the invisible ultraviolet emission lines from the excited argon. 👉 Argon Glow Discharge Lamp: the light from this bulb comes from the 120 volt AC excitation of argon gas that produces a characteristic emission spectra, the components of which include many lines in the violet as seen through a diffraction grating. 👉 Slinky Treadmill- repost of a favorite from exploratorium: kinetic motion energy transfers to elastic potential energy and then back to kinetic energy in a cycling process as a slinky spring "walks" down an incline. Put the system on a treadmill, such as this one at the Exploratorium in San Francisco, and the walking behavior can be explored for many minutes. Note that after a while the slinky's walking becomes erratic.👉 Faraday Train: two magnets, one battery, and a coil of bare copper wire are the simple essence of this self propelled craft.👉 Rotational Instability: this bowl shaped top will always flip over when spun. A complicated dance and interplay of angular momentum, friction, and torque. 👉 Magni-Orb: kinetic art as oscillations about a magnetic equilibrium point. The base and sphere are carved from rosewood and have strong magnets embedded within them that produce an attraction. If the sphere is given some initial rotation it will exhibit complex orbits as the energy trades back and forth between potential energy and kinetic energy. 👉 Coins and Eddy Currents: coins interacting with powerful neodymium magnets. Eddy currents are generated when conductors move near magneticfields- these currents then produce opposing magnetic fields. Coins that are made of good conductors fall slowly through the magnets (quarters, dimes, and pennies) and those made from poor conductors fall faster (nickels).👉 Electric Motor: in its simplest form!- coil, magnet, and battery. The wire of the coil has an insulating coating- and this coating is carefully scrapped off one side on each end.👉 Thermochromic Chiral Liquid Crystals: the thin layer changes color as the molecules of the liquid crystal change orientation and spacing during the phase transition from liquid (warm) to crystal (cool).Background music by1) Finesse by Peyruis Commons — Attribution 3.0 Unported  — CC BY 3.0 promoted by Audio Library Track: Cartoon - Why We Lose (feat.
