spYke Ferrofluid Display Cell: another spectacular display cell by @czferro featuring a colloidal ferromagnetic liquid in a specially prepared water-alcohol suspension. The orange background highlights the curious spiking behavior of the black ferrofluid- a result of the interplay between magnetic force and surface tension between the liquids. 🌟Special thanks to @czferro of Concept Zero design studio for this beautiful display! ➡️ Follow the link in my @physicsfun profile for info on where to get this and other amazing ferrofluid displays. #ferrofluid #fluiddynamics #magnets #magneticfield #magnetism #colloidal #physics #physicstoy #science #surfacetension #neodymium #conceptzero #scienceisawesome #electromagnetism

High Voltage Wood Burn: my attempt to make a Lichtenberg fractal by applying a high voltage electrical current across a piece of wood. Inspired by the fractal in my previous post, I realized I had all the equipment needed in my garage including a neon sign high voltage transformer. Here is the burning process using 7500 V at 20 mA. I turned the power off right before the two sides connected to get the fern-like look. The wood is slightly wetted with baking soda dissolved in tap water. ‼️WARNING high voltage can kill- do not use a transformer like this unless you are fully trained in electrical high voltage safety. ➡️ Follow the link in my profile for info on how to obtain a fractal like this and other amazing items featured here on @physicsfun #Litchenberg #frozenlightning #fractal #electron #physics #physicstoy #mathtoy #mathstoy #electromagnetism #science #lightning #highvoltage #scienceisawesome #electricity #arc #electricarc #fractalart #beamtree #fractalsculpture

High Voltage Fractal in Wood: a Lichtenberg fractal created by a high voltage electrical current flow across a piece of wood. Since wood is an insulator a light coating of conducting water (for instance a solution of baking soda or salt) is first applied to the surface. Metal electrodes are then attached at each end of the wood piece and a dangerous source of high voltage is applied (such as a microwave oven transformer or neon light transformer). This beautiful piece was crafted by Matt Dombroski @EngravedGrain. ➡️Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun #Litchenberg #frozenlightning #fractal #electron #physics #physicstoy #mathtoy #mathstoy #electromagnetism #science #lightning #highvoltage #scienceisawesome #electricity #arc #electricarc #fractalart #beamtree #fractalsculpture

Toroflux: kinetic art toy made from a single continuous loop of stainless steel band. The band of spring metal is woven such that it forms a torus that can clamp on to and roll down a stick, segment of tubing, or even an arm. Amazing combination of math and kinetic art invented by Jochen Valett. ➡️ Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun #toroflux #torus #springmetal #kineticart #hookeslaw #springforce #kinetic #toroflux #flowring #kineticenergy #physics #physicstoy #mathtoy #mathstoy #science #scienceisawesome

Centripetal Spheres: two ball bearings connected by a rubber band orbit each other as energy oscillates between elastic potential energy and rotation kinetic energy. Just wind up the rubber band and let go. When the rubber band has unwound the rotational inertia of the bearings winds it back up until it changes direction. The process repeats until the initial energy is dissipated through friction. ➡️ Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun #centripetal #physics #physicstoy #kinetic #kineticenergy #kineticart #elastic #elasticenergy #ballbearings #sphere #rotationalkineticenergy #angularmomentum #science #scienceisawesome

Memory Spring: some special alloys of brass can be made to have a shape memory triggered by temperature. These springs quickly change their length from 1 cm to 2.5cm when heated above 90 C (done here with hot water) and just as quickly shrink back to original size when cooled (immersed in cold water). Useful in many applications, especially things like automatic fire sprinkler valves. This amazing property is probably due to a solid state phase transition similar to that of Nitinol wire called a martensitic transformation. ➡️ Follow the link in my profile for information on where to buy this and other amazing items featured here on @physicsfun #memorywire #physics #physicstoy #phasetransition #martensitic #memoryalloy #nitinol #alloy #thermodynamics #statisticalmechanics #thermostat #science #scienceisawesome

Star Wars Mirror Illusion: Symmetry + Reflection = Illusion. A two sided mirror and symmetric images combine to make this Taco Bell toy from 1996. ➡️ Follow the link in my profile for info on where to buy this and other amazing items featured here on @physicsfun #mirror #reflection #symmetry #optics #illusion #physics #physicstoy #starwars #yoda #darthvader #tacobelltoy #science #scienceisawesome

Anamorphic Business Card: the actual business card of the inimitable Tim Rowett, the amazing Tim the Toyman of YouTube fame. I have Tim to thank for many of the curious and fun items in my collection. ➡️ Follow the link in my profile for info on where to buy most of the amazing items featured here on @physicsfun #physics #physicstoy #anamorphos #anamorphosis #anamorphicart #TimRowett #businesscard #grandillusionsinc #science #scienceisawsome

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! ➡️ Follow the link in my profile for information on where to get this device and many other amazing items featured here on @physicsfun #jansen #theojansen #strandbeest #wind #windpower #linkage #jansenslinkage #physics #physicstoy #noncirculargear #sungear #geartrain #science #kineticsculpture #kineticart #art #torque #scienceisawesome

Magnetic Top and Snake: the magnetic tipped top stays on the perimeter of the steel snake- but since the top has much more mass, the snake moves the most slithering to and fro. This kinetic art toy has been around for decades and takes advantage of Newton's 3rd law and rotational kinetic energy. ➡️ Follow the link in my profile for info on where to get tops like this one and other amazing items featured here on @physicsfun #top #spinningtop #vintagetoy #newtons3rdlaw #physics #physicstoy #angularmomentum #relativemotion #magneticfield #magnetic #kineticart #science #centerofmass #magnetictop #scienceisawesome

Cartesian Diver: increasing pressure on the water compresses the air bubble in the small plastic vial (here in the shape of an octopus' head) filling it further with water and making the diver sink. Pascal's principle states that any change in pressure on an enclosed fluid (such as squeezing the plastic bottle) is transmitted evenly to every part of the fluid- the physics of hydraulic brakes! The physics here is great- but the biology is questionable: it's not clear why an octopus would need mask and snorkel! (Its tentacles look cool though...) ➡️ Follow the link in my profile for info on where to get this and many more of the amazing items featured here on @physicsfun #hydraulics #physics #physicstoy #fluidstatics #ReneDescartes #cartesiandiver #Archimedesprinciple #pascalslaw #BlaisePascal #buoyancy #science #scienceisawesome

Strobe Coin Spinning Top: beautiful coin tops made of solid copper and silver display a remarkable spinning strobe pattern when viewed on video from a smartphone. Incredible art/physics from @shirepostmint that takes advantage of aliasing and the wagon-wheel effect. The black enamel pattern on the top of the coin is specifically designed to interact with the frame rate of the video process to produce the intricate motions of the concentric circle patterns seen here, and on the back of the coin a starburst pattern provides similarly interesting effects. These coins can be spun on both sides with spin times reaching 12 minutes! The contact points are super hard spheres of silicon nitride black ceramic (Si3N4) providing a low friction bearing. ➡️ Follow the link in my profile for information on where to buy these and other amazing items featured here in @physicsfun #physicstoy #executivetoy #coin #cointop #strobetop #pockettip #spinningtop #angularmomentum #physics #rpm #aliasing #wagonwheeleffect #science #scienceisawesome
