One method used was to pump liquid nitrogen into the rock, freezing the water until the cut could be sealed.

This works by pumping liquid aluminium into a chemically bonded sand mould from below.

Included in the interactive exhibits are pulley-blocks, a water wheel, and a human-powered impeller for pumping liquids.

Hydraulic fracturing involves pumping liquids into the ground to generate cracks within geologic formations to increase access to liquids and gases trapped within those formations.
