Apparently they have found what is being called a FATBERG (fat+Iceberg) weighing 1/4 million pounds (was supposed 130tonnes as they listed it meaning 130x1000kg or 2200lbs) either way its apparently twice the length of 2 soccer fields (250m the article says). It has apparently clogged a massive sewer pipe in London and has nearly turned into the consistency of concrete made of fat, diapers and all kinds of disgusting stuff.. THey are claiming it could take 3 weeks to clear the pipe.
