Split Vortex Marble: What does a vortex marble look like from the inside? Here are two examples of this amazing lampwork art: a split vortex marble by Raven Copeland aka @madglasser, and a classic vortex marble by the inventor of the art form Kevin O’Grady @kevinogradyglass (swipe to view). This rare split marble has been cut down the symmetry axis of the spiral and polished to reveal the inner workings of the vortex marble illusion, where the spherical clear glass face of such marbles acts as a convex lens giving the illusion that the spiral goes deeper than the diameter of the marble.

Manipulable Exhibition: an incredible interactive souvenir from artist Felipe Pantone’s recent solo exhibition at @gallerycommon entitled “Manipulable”. Pantone takes op art to the next level- mixing physics and the psychophysics of vision within forms that invite physical interactivity, astounding the senses and giving new insights to our perception. I’m eternally grateful to Galley COMMON for sending me this opening day souvenir for my collection.

Double Pendulum with Glow Tracer Screen: A UV diode traces the intricate path of the pendulum on to a phosphorescent screen, revealing its chaotic motion. It’s amazing that such complex motion can arise from a simple assembly of two pendulums, one attached to the end of the other. Chaotic motion, such as that observed here, is characterized by extreme sensitivity to initial starting conditions, tiny differences in how the system is released leads to dramatically different outcomes each time.

Visit the Exploratorium 

Spindrift @exploratorium: surprisingly complex and graceful motions arise when rings are set to roll on a parabolic surface in this exhibit created by artist Shawn Lani at the Exploratorium in San Francisco. As the energy of the ring's center of mass trades to and fro from potential to kinetic, odd motions such as flip-flops, figure eights, and quick spins can occur in a determined but chaotic fashion. ?

Mercury Fountain of Calder

This fountain is on display here:

Visit: Fundació Joan Miró

Here is a discription of the artwork by the artist Calder himself.

See my other posts: cautious fun with mercury

Mercury Fountain: Some amazing physics fun from my January holiday in Barcelona- a fountain of flowing metal with 150 liters of mercury filling a two meter in diameter reflecting pool. This fountain is kinetic art created for the 1937 World’s Fair in Paris by the famous artist of mobiles, Alexander Calder, and features aspects of his trademark design. Given the density of mercury at 13.5 g/ml, the liquid in the fountain weighs in at roughly 2000 kg (4500 lbs), and at the bottom of the fountain Calder utilizes the small but massive droplets to impact a paddle which keeps the mobile components in motion. This work also has important historical significance as a political statement against injustice. Note that the top of the mobile includes, in cursive, Almaden, in remembrance of the mercury mining town that suffered under Franko’s siege during the Spanish Civil War in 1936. The fountain now sits behind thick sealed glass on display in the Joan Miró Foundation museum atop Montjuïc in Barcelona.

Moon Globe with Raised Relief

Get this incredible globe here:

From Etsy: BUY NOW: Terrainian Space Globes

Moon Globe with Raised Relief: explore our Moon in your own hands with this incredibly detailed lunar globe where all surface features have been rendered in 3D topographic relief- where the mountains and craters actually cast shadows. Note how the selenography of the far side is radically different from the familiar near side- with no flat maria plains- and craters stacked upon more craters. Humanity has only known what the far side looks like since 1959 when the Soviet spacecraft Luna 3 took the first photos, and the Moon’s full map was completed via NASA’s Clementine orbiter in 1995- the data upon which this globe was made. Shown also are the six Apollo landing sites where humans have left footprints in the lunar regolith. This globe is made by Jeff Hobbs of Terrainian Space Globes by a process of precision CNC machining and cold casting techniques, complete with space-age look base stand. 

Cartesian Jellyfish Divers

Get these charming jellyfist here:

From Amazon: BUY NOW: Jellyfish Divers

Cartesian Jellyfish: increasing pressure in the water compresses air bubbles inside the plastic capsules, filling them further with water making them sink in this cute version of the famous Cartesian Diver toy. In this whimsical version the jellyfish also spin when the pressure is released as the water is channeled out of the capsule/head in a sideways jet. 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! Named after the physicist and philosopher Rene Descartes.

Visit the Exploratorium 

Avalanche @exploratorium : Spontaneous stratification from pouring granular mixtures. Typically pouring stuff together results in further mixing, yet here the result is an ordered sorting into layers. The larger rounded dark grains separate from the smaller sharp-edged white grains forming the layers you see here. The darker grains alone would stack into a steeper pile (larger angle of repose) than the white which would form a less steep pile. An amazing physics discovery of the 1990s showcased here by Ken Brecher and Erik Thogerson.? With special thanks to the Exploratorium!
