The orbit of the magnetic ball can be set to any period but also has default selectable presets to indicate the current hour, minute, or second. This kind of levitation uses a control system with adjustable electromagnet coils in a feedback loop with Hall effect sensors which allow for fine tuning of a magnetic field to precisely balance the pull of gravity. 👉🏻 Boiler Pen: a miniature “hand boiler” is built into the top of a pen in this odd vintage item in my collection. 👉🏻 Countdown Dice: roll these d24 dice carefully and the number on the top surface will count up or count down in sequence! The geometric form that allows this behavior is called a sphericon, a convex solid discovered by David Hirsch that has the properties of a developable roller, a shape where every part of its surface makes contact with the plane on which it rolls. 👉🏻 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. Sadly I could not make the trip to Tokyo to see these latest works, but I’m eternally grateful to Galley COMMON for sending me this opening day souvenir for my collection. 👉🏻 The Milky Way in a Sphere: the distribution of stars in our home galaxy, laser etched into a crystal sphere, according to the most recent telescopic surveys and mappings- including the stars in the Sagittarius Dwarf Galaxy (a small galaxy that is simultaneously orbiting and getting absorbed into the Milky Way) and the major globular clusters outside the main disk. 👉🏻 Universe Sphere: 380000 laser etched dots, each dot representing a galaxy of stars, reveals the largest scale structure of our universe. This glass sphere contains a 3D mapping of galaxies in a volume of our universe spanning 800 million lightyears in diameter, and matches the clumping and distribution as seen by automated telescopic surveys such as that found in the Sloan Digital Sky Survey data. Hold a chunk of the universe in your hand! 👉🏻 Spherical Dice 👉🏻 Unusual Dice Collection @physicsfun 👉🏻 Hearing Light Modulation: a solar cell connected to a simple amplifier becomes a transducer converting changes in light intensity to sound waves of equal frequency. Here we use the transducer to investigate the dimming settings of an LED flashlight. Unlike incandescent filament bulbs which can be dimmed just by decreasing the voltage or current, LEDs light up upon a threshold voltage- and sophisticated circuits are used to dim the light by rapidly switching the LED on and off. The physiology of our eyes is such that such rapid flickering blurs together, but our ears can perceive much higher frequencies as a tone. When the light is at its brightest there is no switching, and hence no sound is produced. However, the various dimming settings produce different tones whose frequencies are equal to the flicker rate of the LED. 👉🏻 Harbottle Balloon Demo: a regular untied balloon remains inflated- one can even look down the neck of the balloon and see inside! Just blow up the balloon inside the bottle and then cork the hole in the opposite end- in so doing the inside of the balloon is experiencing the full force of air pressure, but the exterior of the balloon is protected from the crush of air pressure by the rigid wall of the bottle. Air pressure at sea level is 10.1 Newtons of force per each square centimeter of area (14.6 pounds per square inch). The bottle allows a pressure differential, pressure on the inside but much less on the outside of the balloon. 👉🏻 Lenticular Lithograph 👉🏻 Viral stuff on internet vs @physicsfun 👉🏻 BONUS CLIPS 👉🏻 SOLUTION TO PREVIOUS QUIZ 👉🏻 PHYSICS BRAIN TEASER 👉🏻 Randomly selected comment Background music by : YouTube Audio Library 1) Liquid Time- Aakash Gandhi 2) Crazy - Patrick Patrikios
