Build It. Shift It. See Mechanical Engineering in Motion.
Go beyond diagrams and theory. Build a working 4-speed gearbox model and explore how gears interact through hands-on mechanical construction.
See How Gears Work Together
As the mechanism moves, the exposed gears make mechanical motion easier to observe. Shift between the four positions and explore how different parts of the gearbox interact — turning an engineering concept into something you can build, move, and examine for yourself.
A Challenge Made for Curious Builders
Building the gearbox rewards patience, concentration, and problem-solving. Piece by piece, teens work through a hands-on mechanical challenge that encourages spatial reasoning and curiosity about how machines work — all without a screen.
