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. Buy physicsfun toys on : https://bit.ly/2MOjFET (Official websit 🇺🇸) physicsfun toys on amazon : https://amzn.to/36RRxt0 Follow on Instagram : @physicsfun This video contains : 👉🏻 The Levitron: spin stabilized magnetic levitation- will fly for about 3 minutes or more per launch. Perhaps the most amazing physics toy ever invented! 👉🏻 Solenoid Magnetic Accelerator: six electromagnet coils push a steel ball to terminal velocity. Each coil is triggered to briefly energized only when an infrared led and sensor circuit detects the presence of the ball. The steel ball’s speed seems limited by the strength of the temporary magnetic field and the friction it encounters from the track. This ring configuration demonstrates proof of concept for a means of accelerating steel marbles and I hope to incorporate these coils in other marble run designs I will share in the future. Uses a 12V power supply. 👉🏻 Wild Eyes Holographic Glasses: put on these goggles and on top of every point-source of light will appear an animated holographic image of sharks swimming. 👉🏻 Buoyancy Discrepant Event: wood that sinks and a rock that floats!- a study in density properties of ironwood and pumice. 👉🏻 Turbine Convection Color Candle: a simple heat engine by designer Achille Castiglioni- rotational motion resulting from the convection of hot air due to the candle flame of a tea light. All moving parts of thin stainless steel with semitransparent colored panels. Energy transfer: chemical bonds to heat to kinetic energy of the rising air to rotational kinetic energy of the turbine. 👉🏻 Vintage Blacklight Poster: a stunning psychedelic era poster from 1969 glows brightly under an LED blacklight in this specially made frame. 👉🏻 Electric Discharge Fractal: the delicate branching structure seen here is a Lichtenberg type fractal created by electron current flow. 👉🏻 In Defiance of Gravity: a 3 oz plumb bob in suspension between a chain and a powerful neodymium magnet. 👉🏻 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. If the images are on top of the plastic they are visible under water, but if they are printed under the plastic the light is bent away from the camera. From the WOW Science magic series by Mark Setteducati. 👉🏻 Quantum Re-Excitation: a green laser should not normally be able to induce a phosphorescent glow, but if the material is already excited a green laser can re-excite it as seen here.
