The Big Machine takes visitors through the working principles of some simple machines; the wedge, lever, inclined plane, pulley and wheel. As users transport the tactile ‘grain’ through the machine’s components it demonstrates how they work whilst engaging in exploration and play. The exhibit enables large groups to engage independently or collaboratively, exploring machines, the movement of materials and energy transfer.
Around the main installation are small satellite exhibits which offer visitors a more in-depth investigation of the simple machines, where they can feel the mechanical advantages of the simple machines and compare the difference between variations on the machines.
The Big Machine exhibit is a collaborative project with the Science Museum in London, and a redevelopment of their hugely popular ’Grain Pit’ exhibit.
