London's 140-ton fatberg was finally pulled from a sewer last year, but it didn't disappear. Samples of the mass of fat, oil, wet wipes, and feminine hygiene products have found a comfortable home in the Museum of London's permanent collection, and you don't need to visit to see them. A hit while on display from February to July, the "highly toxic pieces of sewage" can be watched slowly decaying any time via livestream, which means avoiding the smell of "dirty toilets," per the Guardian. Alas, the stream is pretty boring, though the fatberg previously changed color, sweated, and hatched flies, reports Smithsonian. Lately, it's started growing mold. (More fatberg stories.)
