Balancing Bottles: serve with physics style this season displaying this design where the combined center of mass of the wine rack and two bottles is directly above the base of the wood rack- because sometimes it takes two bottles of wine to bring life into balance! 🍷😜 ➡️ Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun #centerofmass #winerack #physics #physicstoy #equilibrium #unstableequilibrium #balance #wine #pasorobleswine #science #scienceisawesome

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. Watch the end with the sound on! ➡️ Follow the link in my profile for info on where buy this and other amazing items featured here on @physicsfun #euler #eulersdisk #spinning #physics #physicstoy #angularmomentum #dissipative #precession #sprolling #precessionrate #spinning #spinningtop #rollingfriction #science #scienceisawesome

Mirror Anamorphosis: this vintage card from 1984 contains a cylindrical mirror anamorphic image. Lady Liberty is revealed by bending the flexible Mylar mirror in to a half cylinder. The math describing this mapping is quite complex and was given in detail in a physics journal in 2000. ➡️ Follow the link in my profile to find where to get the amazing items featured here on @physicsfun #math #mathtoy #anamorphos #art #physics #physicstoy #mirror #cylinder #istvanorosz #science #anamorphic #anamorphicart #scienceisawesome #anamorphosis #cylindrical #perspective #mirroranamorphosis #mathstoy #geometricprojection

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

360° Photopolymer Reflective Hologram: one of my favorite pieces of holography- Batman from the Saga of the Dark Knight card series 1994. 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. Looks even more stunning in person! ➡️ Follow the link in my profile for info on where to buy this and many other amazing items featured here on @physicsfun #physics #physicstoy #hologram #holographic #interference #optics #photopolymer #photopolymerhologram #batman #darkknight #skybox #laser #science #scienceisawesome #dccomics #throwback #skydisc

Balance Squid: everyone’s seen the balance bird- so how about a balancing cephalopod? The weight of the primary tentacles create a center of mass below the squid’s beak- making a system in stable equilibrium on its custom stand. No magnets! ➡️ Follow the link in my profile for info on where to get a balancing squid and many other science curiosities featured here on @physicsfun #equilibrium #centerofmass #physics #physicstoy #balance #cephalopod #squid #balancebird #rotationalinertia #science #scienceisawesome #stableequilibrium

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

The Lollipopter: one of my favorite interactive kinetic sculpture designs. With a bit of practice one can master the transformation in both directions: A snap of the wrist imparts angular momentum to the "petals" which then rotate until an internal mechanism stops their motion with predetermined spacing- a helix transforms to an abstract pine cone. A second snap of the wrist in the opposite direction returns the helix.

Hand Boiler: liquid-gas phase transition. The boiling point of dichloromethane is slightly below body temperature - heat from a hand increases pressure in the bottom bulb pushing the purple (dyed) liquid through the glass pipe to the top. ➡️ Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun #thermodynamics #phase #physics #physicstoy #phasetransition #phasechange #heat #handboiler #dichloromethane #idealgas #pv=nrt #science #scienceisawesome

Ferrofluid Interactive Lava Lamp: special ferrofluid infused wax allows manipulation of the blobs of “lava” with a weak magnet, adding an interactive element to the already mesmerizing physics of convective heat flow, Archimedes principle, and immiscible liquids. Love the atomic rocket theme on this updated version of the 1960s classic physics toy. ➡️ Follow the link in my profile for info on where to buy this and other amazing items featured here on @physicsfun #lavalamp #thermodynamics #convection #archimedesprinciple #physics #physicstoy #physicsfun #heatflow #fluiddynamics #ferrofluid #magneticfield #science #scienceisawesome

Chaotic Coupled Rotors: kinetic energy is passed back and forth chaotically due to magnets mounted on the the ends of the spines that repel. This toy was marketed under the name Magnetron and sold in the Natural Wonders shops in the 1990s-sometimes available on eBay. ➡️ Follow the link in my profile for info on where to get the amazing items featured here on @physicsfun #chaostheory #physics #physicstoy #physicsfun #magnets #magneticfield #science #nonlinear #nonlineardynamics #magnetron #strangeattractor #angularmomentum #force #scienceisawesome
