1. The biggest ‘fatberg’ found in London sewers was 250m long and weighed 130 tonnes

A ‘fatberg’ is the term coined for an increasingly common blockage found in London sewers. It happens when so-called ‘flushable’ wet wipes mix with cooking fat that is poured down the sink. The biggest ‘fatberg’ was found in the London borough of Whitechapel in 2017. It weighed 130 tonnes (the same as 11 double-decker buses).

It took a team of 8 workers 3 weeks to remove the blockage. They were wearing Hasmat suits and used high pressure hoses and pickaxes to remove 20 to 30 tonnes per shift.

2. Cows produce between 100 and 150 litres of saliva a day

The cow saliva has three purposes:

  1. Lubrication – To help the grass and debris slide down the oesophagus.
  2. Fermentation – Copious amounts of liquid help the fermentation process that occurs in the rumen (fermentation vat). The rumen contains between 1-10 billion bacteria per ml. The bacteria break down the vegetation so that the cow can digest it.
  3. Acidity regulator – The saliva is an alkali which helps balance the ph in the stomach as so much acid is produced during digestion.

8. A British Aircraft safety video was so horrific that 13 people required medical attention

At a British Aircraft Corporation factory, in Preston in 1978, manager Ron Hesketh showed the employees a safety video about the importance of wearing safety goggles. It was so graphic that it caused thirteen employees to need escorting out and attended to by state registered nurses.

The video showed, in gruesome detail, what happened to employees who didn’t wear eye protection. One scene was so realistic that a welder fell off his chair in fright and had to have seven stitches. During the same scene another worker fainted and had to be carried out. A close-up of another accident was so shocking that a group of machine minders had to be led out feeling sick and faint.

The safety video was banned because it was deemed too dangerous. Hesketh said ‘We are keen to get over the point of eye protection but at this time we have decided not to take any chances.’

9. Ancient Romans used human urine for toothpaste

Roman toothpaste formulas made use of both human and animal urine. The ammonia in urine would have helped to whiten the teeth, although how clean they were is open to debate!

Romans also used urine to clean clothes. They had public pots where people could urinate. The urine was then left until the ammonia had killed the bacteria. Then the urine jars were collected and the urine was watered down and used in launderettes as a cleaning agent.

Ammonia is still used in modern day cleaning products, but it is manufactured rather than collected from urine.
