I was out later this afternoon and bought a toy from a Charity shop here in the UK.
It is called Euler's Disk.
A little like a spinning top, a little like a very heavy large and thick 3 inch coin that you spin sideways- and very much like a gyroscope, but much more fascinating for some reason.
It has holographic like magnetic pattens that stick on to the large metal disk that spins to add effect and amazing visuals. It all spins- started from hand for up to 2 and a half minutes! And it does too- manged 2:10 this afternoon!
It all spins on quite a large slightly concave mirror- very similar to the type used in a reflecting/Newtonian reflector Telescope.
The piece de resistance though is to get the heavy disk set up and spinning- then fire a hand held laser pointer at it - then turn the light off in the room and view the truly amazing circular arcs etc. patterns that reflect on to the room ceiling and walls. INCREDIBLE!
Mind blowing- worth every penny - I did a quick look, here is more!
Euler's Disk - Wikipedia, the free encyclopedia
and more here!The Official Euler's Disk Website
and in there, more on the recent toy, and the historyhttp://http://www.eulersdisk.com/History.pdf
YOU TOO CAN SPOLL!!!!
Fascinating, truly Fascinating.
cheers,
Dave
