The imagination no limits, very good kombinjerbar with Duplo bricks & Co. However, there is only "normal" orbital elements (straight, 90 ° curve, curve 180 °, downhill portion or bevel shaft or inclined plane or ramp and end piece / early stone). With us, the inclined planes are always the first, since you need this to keep the balls going. We have already built a number of launches (then the ball falls from the 2nd channel somewhere in the original track) and looked who is faster, etc. As we had too little ramps we have already taken Duplo roofing tiles (right and left of it a wall built so that the balls do not slip out sideways) - went halfway.
For us a great track (which until now - mainly to build the adult ;-) - 2 weeks in use) where really many Duplo (-like) stones as a framework (substructure) are needed. Also sufficient building boards should be ready. There are at sufficiently plastic balls, conventional marbles are also useful. Who special effects is expected to wrong here.
