London England had it's hands full this past week as they removed a 15 tonne fatberg from the Kingston suburb sewer line. The berg was discovered when locals started complaining about not being able to flush their toilets. It took 10 days to remove the mass of fat.
Fatbergs like this occur from people pouring fats like frying oils down the sinks and toilets. They build up on the walls and then other wrongfully flushed items like baby wipes stick to it.
This same effect can occur in the pipes of your own home if you are not careful and can be very costly. Dispose of fats in jars and take them to the garbage. We don't need any fatbergs clogging up our pipes. Gross.
