Amazing Science Toys/Gadgets 9

Hi Everyone :)
Welcome back!

Thanks for watching Amazing Science Toys/Gadgets 9

I get asked often: "Where did you get all this stuff?" My goal is to share the real magic of science and physics- and to this end I will update here (and in my store) suggestions on where to get some of these toys, kinetic art pieces, and scientific curiosities for yourself.
Purchasing items from the links on these pages will help support my IG page of science and wonder.

👉🏻 This video contains and involves phenomena in each clips :

00:00 Satisfying Hexagons: this delightful kinetic art manipulation toy features 19 nested hexagons within a hexagonal frame.
(math, 3d printing, geometry, math puzzle, physics toy, science)

00:27 THE RAYY Fine Jewelry: computational caustic projection from the polished surface of a ring of white gold.
This is not a hologram, but instead a new proprietary light redirection technology by the company RAYFORM.
(nerd jewelry, computational caustics, optics, fine jewelry, reflection, wave interference)

00:55 Digital Sundial: a complex array of thinly layered microlouvers allows the control of transmitted sunlight depending on angle- this one designed for 30-40 degrees latitude.
(astronomy, sundial, digital sundial, sun)

01:17 Buoyancy Discrepant Event: wood that sinks and a rock that floats!- a study in density properties of ironwood and pumice.
(buoyancy, fluid dynamics, physics, achimedes, archimedes principle, bouyant force, ironwood, science)

01:32 Stirling Engine: an elegant model of an external combustion heat engine with dual reciprocating pistons which operates by cyclic compression and expansion of air.
(thermodynamics, physicsfun, heat engine, engine, stirling, energy)

02:00 Splat Pig Ball: water filled ball made of an extremely elastic and sticky (tacky) soft polymer
(splat pig, splat ball, polymer, hookes law)

02:25 Labradorescence: the unique luster given off by the mineral labradorite that appears as a glow emanating from below the surface of the polished rock.
(mineral, mineralogy, geology, geophysics toy)

02:48 Electromagnetic Levitation Module: this engineered control system uses adjustable electromagnets (four copper coils) and and two Hall effect magnetic field sensors (held firm embedded in white silicone) to levitate a 5cm diameter neodymium magnet platform about 3 cm in mid-air.
(neodymium, levitron revolution, magnetic, magnetic field, hall effect, electro magnet)

03:16 Magnetic Influence on Aluminum: physics puzzler- spin a magnet under a beer can suspended by a thread, and the can will turn. Why? Aluminum is not ferromagnetic, and as shown, magnets are not attracted to the can.
(physicsfun, physics demo, lenzslaw, faraday, magnetic flux, neodymium, eddy current, science is awesome)

Answer: the can spins due to eddy currents induced in the conducting aluminum due to the moving magnetic fields underneath. The eddy currents make the can into a temporary electromagnet that then attracts the magnets below according to the famous law by Lenz.

03:56 Twin Fan Lissajous: two rotating fans with LED lights form Lissajous figures when spun around common axis.
(harmonic, harmonic motion, LED light show)

04:29 String Shooter: a loop of multicolored string projects upward pushed by two motorized wheels in the base. (kinetic energy, kinetic art)

04:50 Chain Fountain: as the chain flows out of the glass under the pull of gravity the beads don't simply roll over the edge but instead arc up upward like a fountain.
(chain fountain, gravity, newton, newtons third law, force, Mould Effect)

05:05 Thermobile: Nitinol wire loop heat engine- (nitinol, memory wire, heat engine , thermodynamics)

05:28 Demonstration of Nitinol Wire

05:44 Memory Spring: some special alloys of brass can be made to have a shape memory triggered by temperature.
(memory wire, memory alloy, thermodynamics, statistical mechanics)

06:01 Precision Stirling Engine: low temperature difference engine turns body heat into mechanical motion.
(heat engine, engine, stirling engine)

06:31 Spiram Siderum: a spiral of foil holographic stars turns on an axis held by magnets in delicate equilibrium against gravity-
(kineticart, neodymium, science is awesome)

06:51 LASER Pointers + Diffraction Grating: three frequencies of laser pointer- Red (635 nm), Green (532 nm), and Blue (450 nm).
(diffraction, interference, two slit interference, quantum mechanics)
