The joys of construction coupled with a seemingly perpetual motion machine. The Ultimate Techno Balls 920 kit provides you with everything you need to construct an intricate dual marble run with two battery operated marble lifts.
There are cogs, chains and twin rails to fiddle with to your heart's delight, and once the build is completed to your satisfaction, add batteries and watch the marbles run and run.
Hours of absorbing fun for techno-minded types. The completed Techno Balls 920 is approximately 96cm wide and 62cm high (about 3ft by 2ft).
To operate the motors, the Ultimate Techno Balls 920 kit requires 4xAA batteries which are not included in the kit.
