Tea-Light Floating Engine
View this post on Instagram

Tea-Light Floating Engine: a candle powered super simple steam engine. The engine is just a coil of copper tubing filled with water. Steam builds up pushing water out with an explosive jet- which then results in a vacuum in the coil which pulls more water in to repeat the process. The water expulsion is in the form of jet directed out the end of the tube whereas the refill comes back in to the tube from a larger range of angles- so on balance the engine moves opposite to the direction of the jets. ➡️ Follow the link in my profile for info on where to get this simple engine kit and other amazing items featured here on @physicsfun #engine #physics #thermodynamics #physicstoy #steamengine #phasechange #poppopboat #science #tealight #scienceisawesome #candle #heatengine

Iron Filing Field Detector
View this post on Instagram

Iron Filing Field Detector: visualizing the invisible- the magnetic field lines around a dipole bar magnet. In the presence of a magnetic field, ferromagnetic materials (such as iron) temporarily become magnets. Here the iron filings become dipole magnets and link up and align like tiny compass needles to follow and reveal the magnetic field lines associated with the permanent magnet underneath. Viscous silicone oil temporarily keeps the iron particles suspended yet allows for rotation and repositioning under the influence of the magnetic field. ➡️ Follow the link in my profile for info on where to obtain this and other amazing items featured here on @physicsfun #physics #magnetic #magnetism #magneticfield #physicstoy #dipole #dipolefield #demonstration #silicone #physicsdemo #horseshoemagnet #electromagnetism #science #scienceisawesome

Plasma Arc Lighter
View this post on Instagram

Plasma Arc Lighter Physics: dual arcs of plasma exceed 1100 C (2000 F) on this flameless lighter. The breakdown voltage of air is about 3000 Volts per mm. Thus the circuit in the lighter must provide about 12,000 volts to produce this 4mm arc. The circuit is a simple one made possible by a transformer with very fine wire windings, a transistor, and a powerful lithium-ion battery (USB rechargeable). The circuit produces high frequency current oscillations in the coils that in turn produce the needed high voltage. Like having a Tesla coil in your pocket! ➡️ Follow the link in my profile for info on where to get this and many of the amazing items featured here on @physicsfun #physics #physicstoy #plasma #highvoltage #tesla #teslacoil #highfrequency #plasmaarc #flameless #transformer #scienceisawesome

Bimetal See-Saw Engine- with Bears
View this post on Instagram

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

Hyperbola Clock: a straight rod glides through a curved hole in this unconventional clock based on the hyperboloid, the 3D ruled surface traced by rotating diagonal line. In this creation by Robert Darwen of Fibonacci Clocks, the rod serves as the hour hand with a smaller minute hand above the center of the base disk.

Euler's Disk: (best with sound on) this toy exhibits the motion of a “sprolling” coin, a motion that combines spinning and rolling. Designed with a large mass and very smooth edge, this device takes close to 3 minutes to come to rest- and amazingly, the contact point between the disk and the mirror can reach a speed of more that 200 mph! This video catches the first and last parts of this 2 minute and 42 second run, with two cuts to 240fps slow motion to show the curious motion.

Tapered Mirrors Kaleidoscope
View this post on Instagram

Tapered Mirrors Kaleidoscope: the unique design of this teleidoscope uses three mirrors to create an image of a geodesic sphere. As can be seen through the semi-transparent acrylic tube, the three mirrors are tapered, with their smaller ends near the ball shaped lens. Three mirrors in an equilateral triangle configuration will produce a plane of tiled triangles, but if they are tapered the repeated reflections curve to infinity creating the sphere. In this design by Koji Yamami there are small gaps between the mirrors which allows in colored light from the iridescent tube to produce the radiant streaks of light. Invented by the famous Scottish physicist Sir David Brewster (1781-1868), the kaleidoscope is an ultimate physics toy and entire field of artistic endeavor. ➡️ Follow the link in my profile to find where to get kaleidoscopes like this and other amazing items featured here on @physicsfun #Kaleidoscope #kaleidoscopic #physics #reflect #teleidoscope #physicstoy #psychedelic #kineticart #science #mirror #symmetry #math #mathtoy #mathstoy #geometry #brewster #Brewstersociety #acyrlic #lucite #scienceisawesome

Please see the next video for details on the physics and symmetries of two mirror kaleidoscopes, and a source of excellent quality (and affordable) scopes.


Kaleidoscope Symmetry Physics

Kaleidoscope Symmetry Physics: Two adjacent mirrors form the repeating image of a kaleidoscope, but the shape of the image is determined by the angle between the mirrors. This principle is demonstrated with three different symmetrical patterns using this beautiful set of precision teleidoscopes- angles of 36° (blue tube), 30° (green tube), and 22.5° (red tube), creating mandala stars with 5, 6, and 8 points. The angle for any symmetric star pattern of n points is just 180°/n. A teleidoscope is a kaleidoscope but with a lens on the end, such that the kaleidoscopic image is formed by whatever is put in front of it. Here the complex motion of a Gyrobi toy is used as the observation object. 🌟Thanks to Leif Colson of @ColoradoScopes for this set! ➡️ Follow the link in my profile to find where to get these teleidoscopes and other amazing items featured here on @physicsfun #Kaleidoscope #kaleidoscopic #physics #reflect #teleidoscope #physicstoy #psychedelic #kineticart #science #mirror #symmetry #math #mathtoy #mathstoy #geometry #brewster #Brewstersociety #gyrobi #scienceisawesome #coloradoscopes

Eclipse: A diamagentic levitation sculpture by Element83
View this post on Instagram

Eclipse: A diamagnetic levitation sculpture by Element83. Cast from diamagnetic Bismuth, a golden spherical neodymium magnet levitates trapped in a tunnel within the metal. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the sphere magnet supplies the field. Diamagnetic fields are pretty weak though so a powerful cube neodymium magnet sits above the tunnel and is adjusted to help lift the sphere magnet against gravity. Trapped in equilibrium by these fields, any other magnet brought near will change the balance. 🌟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 #eclipse #equilibrium #pyrolyticgraphite #scienceisawesome

Spinning Liquid Wave Toy
View this post on Instagram

Spinning Liquid Paperweight: two immiscible liquids (three if you count the air bubble) are sorted under gravity by density with the densest on the bottom and the lightest on top. If the container is rotated the boundary between the layers forms a parabola due to the added influence of centripetal acceleration. As seen here in 240 fps slow motion, symmetric waves travel and reflect along the curved surface for the first few rotations until damped out via viscosity and friction. The plastic fish have a density between that of the two liquids so they stay at the boundary layer. ➡ Follow the link in my profile for more info about where to find this and other amazing items featured here on @physicsfun. #exploratorium #physics #physicsfun #physicstoy #centripetalacceleration #spincam #angularmomentum #parabola #parabolic #pascalsprinciple #hydrostatics #spinning #kineticart #science #scienceisawesome

Incredible 3D image by Skybox International- rotate the disk to reveal an animated 360 degree view. Unlike photographs, holograms are recordings of the interference pattern of light waves. This interference pattern can encode moving 3D images which are then reanimated by illumination with a point source of light and viewing from an appropriate angle.

Scale Model: Pluto-Charon Binary System
View this post on Instagram

Scale Model of Pluto–Charon Binary System: shown here with each in orbit around their common center of mass. The orbit distance of Pluto’s primary moon Charon is only 8.2 Pluto diameters away (very close!), and because Charon is 1/2 the size (and 1/8 the mass) of its parent planet, their common center of mass is far outside Pluto’s surface. (For comparison our Moon is 30 Earth diameters away.) This model also correctly shows how both Pluto and Charon are in tidal lock with each other- one side of Pluto always faces one side of Charon, so the orbit period of Charon is equal to one Pluto rotation (6.4 Earth days). I constructed this model using a 3D printed Pluto and Charon set made by George Ioannidis (based on image data from the New Horizons spacecraft) Scale: Earth diameter = 12 inches. ➡️ Follow the link in my profile for info on where to get a Pluto/Charon set and other amazing items featured here on @physicsfun #physics #physicsfun #physicstoy #scalemodel #orbit #transneptunianobjects #binarysystem #pluto #charon #centerofmass #barycenter #newhorizons #3dprinting #newhorizonsspacecraft #tidallock #tidallocking #astronomy #science #scienceisawesome

Neon Flicker Flame Skull Bulb
View this post on Instagram

Neon Flicker Flame Skull Bulb: no flame but instead emission spectra from excited neon gas due to the presence of a discharge electric current. The breakdown voltage of a gas (the minimum voltage needed for a current to flow) depends on the pressure of the gas in the bulb. The flickering effect comes about because the current flow will increase the temperature near it, which lowers the pressure and affects the breakdown voltage near the current- so the glow from one area can only last as long as it takes to heat up and raise the breakdown voltage which kills the current in that area. In other physics, a diffraction grating shows that neon only emits light in specific wavelengths- mostly reds and yellows at AC house voltages. 🎃 Found this awesome bulb in the Halloween section at my local Target store. ➡️ Follow the link in my profile for info on where to get this and many other amazing items featured here on @physicsfun #neon #emissionspectra #excitation #spectra #breakdownvoltage #paschenslaw #glowdischarge #glowdischargetube #diffraction #diffractionglasses #lightbulb #noveltybulb #science #skull #halloween #scienceisawesome

Wobblo: curious kinetic art toy- a hollow plastic torus contains a rolling heavy steel ball within. The motions of the center of mass of the ball and torus combine dynamically- the resulting curious motion is related to the interplay between the exchange of kinetic and potential energy and conservation of angular momentum of the system. The concave mirror keeps the toy from rolling out of frame for the video.

Kaleidoscope Symmetry Physics

Kaleidoscope Symmetry Physics: Two adjacent mirrors form the repeating image of a kaleidoscope, but the shape of the image is determined by the angle between the mirrors. This principle is demonstrated with three different symmetrical patterns using this beautiful set of precision teleidoscopes- angles of 36° (blue tube), 30° (green tube), and 22.5° (red tube), creating mandala stars with 5, 6, and 8 points. The angle for any symmetric star pattern of n points is just 180°/n. A teleidoscope is a kaleidoscope but with a lens on the end, such that the kaleidoscopic image is formed by whatever is put in front of it. Here the complex motion of a Gyrobi toy is used as the observation object. 🌟Thanks to Leif Colson of @ColoradoScopes for this set! ➡️ Follow the link in my profile to find where to get these teleidoscopes and other amazing items featured here on @physicsfun #Kaleidoscope #kaleidoscopic #physics #reflect #teleidoscope #physicstoy #psychedelic #kineticart #science #mirror #symmetry #math #mathtoy #mathstoy #geometry #brewster #Brewstersociety #gyrobi #scienceisawesome #coloradoscopes
