Bimetal See-Saw Engine- with Bears

Bimetal Seesaw Engine: candle powered heat engine- with bears! A coiled bimetal strip, like that found in a thermostat, coils tighter when heated by the flame moving a counterweight that shifts the center of mass to the left and takes the coil out of the flame. The coil then cools returning the counterweight to the right which places the coil back over the flame- and the process repeats until the candle burns out. Any device that converts heat energy into mechanical motion is called a heat engine- like the very simple one here. ➡️ Follow the link in my profile for info on where to get this and many other amazing devices featured here on @physicsfun #physicstoy #heat #heatengine #bears #thermodynamics #bimetal #bimetalstrip #thermostat #coefficientofexpansion #candle #candlelight #seesaw #periodicmotion #scirnce #scienceisawesome

Gauss Gun

Gauss Gun: acceleration of steel balls through magnetic potential energy and cascading collisions. Four neodymium magnets provide the potential energy that is converted into significant kinetic energy of the end steel ball. The initial configuration has two steel balls on one side of each magnet- an incoming ball on the opposite side accelerates and impacts each magnet in turn sending each loosely connected second ball off with greater speed. ➡️ Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun #gaussgun #magnet #magnetic #electromagnetism #momentum #conservationofmomentum #impulse #magneticfield #cascade #potentialenergy #physics #physicstoy #collisions #science #scienceisawesome

The Alchemist: Bismuth Diamagnetic Levitation Sculpture

The Alchemist: cast from diamagnetic Bismuth, a neodymium cube magnet levitates trapped between the hands of the ancient scholar. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the cube shaped magnet supplies the field. Diamagnetic fields are pretty weak though so a cylindrical neodymium magnet hangs above the figure and is adjusted to help lift the cube magnet against gravity. Trapped in equilibrium by these magnetic fields, the slightest air currents can send the cube magnet dancing. Although alchemists never succeeded in transmuting lead to gold, in 1981 physicists used the particle accelerator at Berkeley to shoot Carbon nuclei at thin foils of Bismuth- the resulting collisions did produced a tiny amount of Gold atoms! So the element Bismuth, with modern nuclear physics, finally accomplished the aspirations of the alchemists. 🌟Another amazing creation by Ernie McElhannon. ➡️ Follow the link in my profile for info on where to get this sculpture and other amazing items featured here on @physicsfun #diamagnetism #physics #physicstoy #neodymium #magneticfield #magnetism #levitation #maglev #science #bismuth #alchemy #alchemist #LBNL #GlennSeaborg #pyrolyticgraphite #scienceisawesome @element83onetsy

Viscoelastic "Melting Snowman"

Viscoelastic "Melting Snowman": non-newtonian flow is demonstrated by these blobs of viscoelastic silicon polymer (aka Silly Putty) in the shape of snowman- if force is applied over a short period of time the substance shows elastic properties (bounces like a superball), but if the force is applied slowly the substance flows like a viscous liquid (flattens under gravity over a few hours as shown here). Thus this snowman does not melt because it is already liquid, one that flows slowly though. Mostly sold as a toy, Silly Putty was discovered after mixing boric acid with silicone oil during World War II in an attempt to find a rubber substitute. ➡️ Follow the link in my profile for info on where to get this and many of the amazing items featured here on @physicsfun #viscoelastic #nonnewtonian #fluiddynamics #nonnewtonianfluid #physics #physicstoy #elastic #dilatant #dilatantmaterial #science #viscosity #coefficientofrestitution #scienceisawesome @educational_innovations #meltingsnowman #snowman

Magneto Aerolux Xmas

Magneto Aerolux Xmas: Wishing all a luminous and Merry Chistmas with a 1930s Aerolux neon dischage bulb powerd by an functioning antique 5 bar telephone magneto generator made in 1910. The generator creates 100+ Volt AC with such a low frequncy one can see the polarity alter back and forth between the electrodes of the flickeing bulb. More on vintage magneto physics in upcoming videos! The letters and background filament glow of the Aerolux bulb with light from the emission spectrum of excited neon. The tree glows green from a coating of phosphor which is stimulated to emit green light by the ultraviolet (and invisible) emission line photons from the excited neon atoms. ➡️ Follow the link in my profile for info on where to get these items and other amazing things featured here on @physicsfun #Aerolux #neon #emissionspectra #emissionlines #light #physics #magneto #telephonemagneto #physicstoy #flourescent #quantumphysics #filament #science #scienceisawesome

Drinking Bird Heat Engine

Drinking Bird Heat Engine: time lapse of 15 minutes into 15 seconds (4 cycles). Cooling by evaporation at the head leads to lower pressure in the top bulb, the dichloromethane fluid rises up the neck making the bird top heavy and the bird tips over dipping its beak and letting the fluid return to the bottom bulb. The time lapse allows a clearer picture of how the fluid rises, shifting the center of mass, and how tipping makes the glass column lift out of the fluid in the bottom allowing the pressure to equalize and letting gravity pull the fluid to return to the base. Process repeats as long as the top stays wet. So much physics in one hypnotic toy! ➡️ Follow the link in my profile to buy one of these birds and other amazing items featured here on @physicsfun #engine #heat #heatengine #thermodynamics #drinkingbird #physics #physicstoy #cycle #timelapse #dippybird #dunkingbird #simpleengine #vaporpressure #latentheat #mechanicalwork #physicsfun #science #scienceisawesome

Self-Propelled Homopolar Motor on Aluminum Foil Racetrack

Self-Propelled Homopolar Motor on Aluminum Foil Racetrack: disk shaped neodymium magnets supply the static magnetic field for this motor and become the wheels of a very simple vehicle with an AAA battery as the energy source. As soon as both ends make contact with the conducting aluminum foil an electric current will flow which in turn induces a magnetic field underneath the battery assembly. This induced field will then interact with the neodymium magnets on each end causing them to spin- a wonderful example of a motor with minimal components. The racetrack is a cardboard circle from a pizza box covered in foil. ➡️ Follow the link in my profile for info about where to get this and other amazing items featured here on @physicsfun #homopolar #motor #homopolarmotor #physics #physicstoy #electromagnetism #magnets #neodymium #ampereslaw #electromagnet #current #aluminumfoil #selfpropelled #science #scienceisawesome

The Ooze Tube

Ooze Tube: viscous polyisobutene fluid timer toy. Some interesting physics phenomena are found in this kinetic art novelty item: the "liquid rope-coil effect" where the fluid thread coils and stacks as it lands on the pooling surface, and a curious periodicity in the rate of flow that is related to the formation of non-spherical bubbles as the air and fluid trade places (shown in time-lapse). The physics of the coiling effect is complex (see the link in my blog). Broadly speaking the coiling is due to the bottom of the fluid rope widening at the contact point with the surface, and as it widens the fluid slows down but not evenly. This uneven rate of flow produces a bend and the elasticity of the stream constrains the rope to a limited radius- hence a stack of coils. ➡️ Follow the link in my profile for info on where to get this and many of the amazing items featured here on @physicsfun #ropecoil #viscosity #fluiddynamics #fluidmechanics #physics #physicstoy #viscousbuckling #geophysics #helix #helicalcoil #liquidrope #liquidropecoileffect #ooze #oozetube #coileffect #kineticart #science #scienceisawesome

Exothermic Crystallization Heat Pack

Exothermic Crystallization Heat Pack: real-time instant crystallization of a supercooled solution. Solid sodium acetate melts at 137F (58C), but it will stay in liquid form as it cools to room temperature creating a supersaturated and supercooled state- the solution stays in the liquid form until a seed crystal, provided by clicking the metal disk, initiates the solidification. The resulting white crystal is actually quite hot; solid states have lower energy than liquid states and thus the difference in energy is given up as heat that raises the temperature back up to the melting temp, and you can see in the few seconds of the video that the temperature rises from 26C to 34C. This pack is reusable many times- just boil the pack until all the crystal is melted to reset. ➡️ Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun #thermodynamics #physics #chemistry #reaction #latentheat #physicstoy #crystal #supersaturated #supercooled #exothermic #heat #meltingpoint #sodiumacetate #seedcrystal #heatpack #science #scienceisawesome
