Audible book too! Will take a look at this. Love this topic.

@CostaCoffee Wow! Accidentally used the wrong (small) cup for my large latte this morning! Not one single drop spilled over the sides of the small cup. 2n picture same coffee transfere to large cup!

Fantastic article by Siemens Robin Bornoff discussing empirical and computational analysis of fluid dynamics, mechanical and optical properties of fluids and rheoscopic fluids. There's a great simulation of a Vortex Dome! blogs.sw.siemens.com/simulat…

Experimenting with ideas for possible future Advanced Gyro accessories. Thought I'd post some here. Quite enjoying this stand 😃 #advancedgyro #gyro #gyroscope #spinningtop #edc #physicstoy #sciencetoy #desktoy #executivetoy #inspiration #workingfromhome

PhysicsHack Advanced Gyro. Unique Gyroscope and spinning top with an infinte drive ratio, can be started simply, and even sped up while in use. Gyros are far more interesting on their side! #gyro #gyroscope #spinningtop #edc #physicstoy #sciencetoy #desktoy #executivetoy

Can anyone help me explain this??? The rotating magnet has poles radially, & the levitated mag has its N pole up. This doesn't work if the S pole is upwards.. it can work axially at the tip of the rotor too?!?!?!? #magneticlevitation #magnet #levitation #magnets #science #physics

Thank you @BexieJames for sending this clip of your Vortex Dome. I hope you enjoy it! #vortexdome #rheoscopic #kalliroscope #rheoscopicfluid #desktoy #physicstoy #fluiddynamics #fluidmechanics #fluids #vortex #vortices #physics #physicstoy

Vortex Dome in Slow motion, my favourite move to give the most defined outline to the pattern of vortices. Google Vortex Dome for more information :) #vortexdome #vortex #fidgettoy #desktoy #rheoscopicfluid #rheoscopic #kalliroscope #fluiddynamics #fluidmechanics

Another magnetic spinning kinetic art desk toy. Energy stored in the wheel animates the ferris type movement. Rotors of varying geometries can be used to show the effect of the moment of inertia.

Magnetic spinning kinetic art desk toy. Energy stored in the wheel keeps this going for some time. Wheels of varying geometries can be used to show the effect of the moment of inertia :)

More playing with the Vortex Dome. Trying out a luminous additive and seeing how the desk toy looks when the rheoscopic fluid is energised with blue and UV light. I enjoy making these similar to the Kalliroscope. This physics toy really shows fluid dynamics. Very mesmerising...

3D Compass shows your approximate latitude by following the true position of North. In the UK where this photo was taken; the Northern Hemisphere the field enters the earth at an inclination shown, it is not parallel to it's surface...

Vortex Domes ready to ship! #fidgettoys #fidgettoy #desktoys #desktoy #sciencetoys #sciencetoy #vortexdome #kalliroscope #rheoscopic

Thanks to the observatory science centre. #oddlysatisfying #physicshack

#Yanny or #Laurel apparently it's to do with pitch, and they are both there... if you hear Laurel however... you old! youtu.be/9PrndtwT-us

Gold Vortex Dome by physicshack

I've made this luminous version with a UV light... youtu.be/VfCq4TgAtEQ

3D Compass, want to get it near a magnetic anomaly area! :) youtu.be/RlN9anRQfIY
