Magnext Dynamix Gears
from Mega Brands

Experiment with magnetic attraction and repulsion using this ingenious set of MagNext Dynamix Gears. Learn to control the way magnets move in relation to each other and metal. Take advantage of a bigger and sturdier pronged building plate upon which to design cool stuff with MagNext standard parts, and then make them spin in different ways. Build a futuristic museum of caged structures, a solar machine or any intricate contraption your imagination allows. Stack the spinning gears as you wish and build as high as you can.
