The museum featured a city street (with cars and motorcycles) with a sewer system that could be crawled through, Grandma's attic with wearable costumes, a large Lego play area, and a section called Sticky City consisting of large stuffed fabric blocks with Velcro that stuck to each other and could be used for building.

There was also a TV studio where children could be camera operators or news anchors, a large photosensitive wall that would imprint shadows when a strobe light was set off, a workshop where visitors could make their own Zoetrope animations, and other activities.

[1] The Little Tokyo facility was indefinitely postponed in October 2002,[2] and while construction of the Hansen Dam facility was begun with bond money in October 2005,[3] the non-profit running the museum was unable to raise sufficient funds to populate the interior.

[5][3][6] The City of Los Angeles entered into a partnership with Discovery Cube Orange County to take over and operate the empty Hansen Dam facility.

[7][8] This satellite campus, named Discovery Cube Los Angeles, opened on November 13, 2014.
