Hybrid Gyroscope Top: the Advanced Gyro is a new design by @physicshack which exhibits a interesting vertical stability phenomenon when placed on this unique stand with three ball bearings that serve to minimize friction and keep the gyro centered. The top defies gravity, due in part to its angular momentum, and its spin axis slowly rises to a stable vertical position from subtle rolling friction interactions with the ball bearings. No pull cord needed, this unique design spins up via friction with a working surface (thin cardboard works well) and applying a circular motion to bring the rotor up to 1000s of RPM. Machined from solid stainless steel this top weighs in at about half a kilo, providing inertia that produces long spin times. Thanks to inventor/designer David Fowler for sending me this fantastic gyro.

From Mr. Sci (Science Factory): Rheoscopic Planet

Rheoscopic Planet: this example of fluid flow kinetic art uses rheoscopic fluid encased in flexible bubble of plastic to reveal the intricate motion of turbulence. A suspension of tiny flat mica crystals tend to align themselves at the boundaries where the fluid is moving comparatively faster or slower, making the typically invisible flow patterns visible. Another unique science toy from @mrscisciencefactory

The Lollipopter

Four styles to choose from: 
From Amazon: BUY NOW: Lollipopter Kinetic Art 

The Lollipopter (The Helicone): 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. A creation by artist John Edmark.

Aquarius Fountain Lamp

Aquarius Fountain Lamp: an oscillating stream of water is illuminated by strobe lights to reveal underlying structures and forms typically hidden from our vision. With the help of programmable micro-controllers, strips of addressable RBG LEDs are made to flash in sequences that make the water stream appear to move upwards, change colors, and split into multiple braided streams. Art meets physics and clever technology in this wonderful creation by computer engineer Stephen Co. With sincere appreciation to Stephen @northerncircuits for sending me one of his hand crafted high tech fountains.

Strandbeest Mini

Get one here! Make sure to get the Jr. Scientist version of this kit for best results. 
From Amazon: BUY NOW Strandbeest Model Kit 

Read about Theo Jansen and his novel leg linkage mechanism for the Strandbeests via these Wiki pages. 

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!

From Amazon: BUY NOW Euler's Disk 

Wikipedia has an excellent introduction to the physics of Euler's Disk 

Eulers 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! 


The Random Walker

Galton Board version available here: 
From Amazon: BUY NOW 
Galton Board 

The Random Walker: second model of two Galton Boards designed and produced by IFA.com- this version is made to demonstrate probability in investment returns of a global stock market portfolio relating to risk capacity. Slow motion reveals the erratic path of each steel ball (second half of video). The red graph shows the distribution of 592 monthly returns (mean =1%, SD=5%) representing data from 50 years of an IFA Index fund- here the random “walk” of 3000 steel balls falling through 12 levels of branching paths always produce a close match, and both distributions tend toward the famous bell curve distribution. A wonderfully designed modern version of the Galton Box invented by Sir Francis Galton(1894) to demonstrate the Central Limit Theorem - showing how random processes gather around the mean.
