Capsela 175 Science Construction Toy System

All of the Capsela Scientific toys are excellent and very well made. I bought these for my son years ago when he was 8 or 9 yrs old. Each plastic cube contains a different set of gears. The guide that comes with the set gives you an explanation of what each gear cube does. This is a teaching toy where the parent has to get involved in order to help understand what each plastic module or cube does. The motors actually do work. This model shown in the picture does actually run. We ran ours back and forth across the dining room table many times. Over all we have four or five different Capsela Toy sets. They are wonderful!
