With Liquefaction, guests control the vibration of a basin filled with small glass beads (blasting media), causing the small house and car structures to sink into the substance. Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loadings.
As the vibration speed is adjusted, the glass blasting media in the basin moves at different rates. Slower speeds create less movement, while higher speeds cause greater movement. By varying the speed, the visitor is able to create multiple scenarios of simulated liquefaction.
The objects inside the enclosure are attached to tethers that guests can move to change the location and to lift the sunken objects out of the media.
