Jaw-dropping Physics Toys/Gadgets 6

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 : 👉🏻 Strandbeest Mini: A fully working model of artist Theo Jansen's Strandbeest kinetic sculpture which features Jansen's linkage- a unique leg mechanism which converts rotary motion of a crackshaft into smooth walking motion. Jansen's creations are usually a couple meters high and walk the beaches of the Netherlands powered by the wind. This version comes as a model kit that snaps together with no glue- a really fun project! 👉🏻 Andrew's Space Wheel: kinetic art desk toy from the 70s- the rotor will stay in motion for weeks, until the hidden 9V battery is depleted. 👉🏻 MetMo Cube: art from precision metalworking technology- a wire EDM (electrical discharge machine) can cut out two ovals from a 0.5 kg cube of solid stainless steel, and leave a gap of less than 0.05mm around the cutouts! 👉🏻 Theo Jansen's Strandbeest kinetic sculpture 👉🏻 Aristotle’s Wheel “Paradox”: How does the smaller attached disk travel the same length as the larger one if both disks only make one full rotation? Note the shorter path of the smaller disk, if rolled on its own. This beautifully made demonstration depicts an issue of geometry and motion that perplexed the best minds of humanity for 2000 years. The ancients knew the formula for circumference, and C=2πR for the large disk is clearly greater than C=2πr for the smaller- so how could the smaller disk, rotated once, still travel the distance of the larger one if attached? The great Galileo even offered a solution to the problem in his book Two New Sciences, where he approximated the situation as concentric hexagons and considered the limit as the number of sides increased. So what is the best answer to make sense of this situation? 👉🏻 Doubly Impossible Bottle: the newest seemingly impossible object in my collection from craftsman/artist Grant Wicks @thebottleologist. 👉🏻 Vintage Selenium Light Meter: selenium metal has a remarkable property- when exposed to light it will generate a small electric current. This General Electric light meter, made in 1930 with classic Bakelite case, still works and needs no battery. 👉🏻 Radiometer in Arylic: kinetic energy from light in this Eames era vintage Lucite block sculpture with encased radiometer. 👉🏻 Parabolic Mirror Array- @exploratorium: 360 mirrors arranged to reflect to a single focal point in this exhibit entitled “All Eyes on Me”. 🌟With special thanks to the Exploratorium! 👉🏻 IMPOSSIBLE BOTTLES @physicsfun 👉🏻 Uplift Kinetic Spiral: black walnut slats comprise a spiral kinetic sculpture under glass, mounted on precision bearings and powered by light.
