McDonald’s Mechanical Model | Trade show scale models

So kids will beg to go there for lunch and to give adults time to eat their hamburgers, McDonald’s sets up elaborate play structures. In order to create new structures and get new ideas, McDonald’s runs a huge trade show to promote new designs.

This particular trade show model involved many interactive play areas and in order to show it properly, we had to motorize four elements. The simplest was the fan and the set of moving gears. Things got more complicated with the “bubblier” game and the large Pachinko machine. Ball bearings were carried to the top on a ladder and dropped randomly over the spikes and wheels below. A water pump created bubbles in tubes showing how kids compete to raise a cone within the tube.
