Watch the Museum of London's Fatberg Sweat and Grow Mold in Real Time

Unlike most other museums exhibits, the fatberg sample at the Museum of London is constantly changing. The chunk of congealed grease and garbage changes color, sweats, and even produces broods of freshly hatched flies. Now, The Guardian reports that you can stay up-to-date on the fatberg's ever-shifting status by livestreaming it into your home.

On August 14, the Museum of London debuted its live FatCam on its website. The dried-out fat glob in the video is one of the last remaining samples of the Whitechapel fatberg, a 143-ton mass consisting of oil poured down sink drains and city litter that was discovered in London's sewer system in September 2017.

From February 9 to July 1, 2018, the museum displayed the unique artifact under three layers of cases for visitors to see. The object proved difficult to preserve, and curators weren't entirely sure it would make it to the end of its exhibition, let alone survive to see another showing.

The fatberg has since been quarantined in the museum's archives. Rather than alter the fatberg to keep it around as long as possible, the museum has decided to broadcast its gradual demise to the world.

In the month since the sample has been taken off display and placed in a special case, drastic changes have been documented. Yellow pustules have surfaced on the fatberg's exterior—a sign of what conservators have determined is the toxic mold aspergillus. The object likely grew the spores when it was on display and only now have they become visible.

Dangerous mold and other organisms living within the crevices of the fat mounds are some of the reasons why the sample is no longer available to view in person. For a safer and slightly less disgusting view of the fatberg, check out the live stream below.
