Cosmos Kinetic Art Motion Toy - Works Great Quick assembly and the inner ring rocks back and forth through the outer ring. There is a 9 Volt battery that goes in the base that pulses a magnetic charge that essentially pushes the magnet in the lower part of the ring perpetually moving the Cosmos forever until the battery wears out. Which takes a very long time. (battery not included....takes any 9 volt battery).
They retail around $29.99 each. This one was barely used or possible never used.
I am in the Eastbridge Area of Waterloo near Rim park just 4 minutes off the expressway (Hwy#85) and University Ave east exit.
Also I can get this delivered to an Oakville location (Also close to Burlington & Bronte ) for pick up near the intersection of Rebecca St. & Jones St. just a 4 minutes off the QEW South on Bronte Road.
