A high-tech version of the Marble Mania Extreme, this 430-piece kit features dual marble tracks, a chamber of sound, a marble twister, a motorized gear and a power lifter that automatically returns marbles to the top of the run. It allows kids to build a bigger and better marble run, and will keep little architects busy creating new working and moving creations. It requires one AA battery. “Our product features several electronic components, such as the sound chamber, the spiral gear and electronic gears. Also, we have a website that gives multiple configurations that can be constructed,” Jaye Ross of The Learning Journey International told TDmonthly. Launch date: February 2007.
