Ready to steal the Duplo toys from your baby boy to build an amazing LEGO marble run machine ? Then Duplo Wave GBC module from Stork might be turning you into a naughty dad. This truly incredible Great Ball Contraption is mainly made with the famous “fat” bricks and it surprisingly runs like a charm. Two plates made with Duplo parts are oscillating, allowing your favorite GBC balls to go from one side to another from the build. Simple but efficient, and a real performance to see this LEGO GBC being built with the bricks from my childhood, or rather my babyhood. If you are the lucky owner of some Duplo vintage gears (I didn’t even know they exist before watching Stork video), this awesome build is waiting for you. Time then to run on free building instructions provided by Stork himself.
