The Truths

Holly Walsh - Insects

- You can use a species of cricket to tell the temperature. In you count the number of chirps the snowy tree cricket, aka the temperature cricket, makes in 14 seconds and add 40, you get the temperature in Fahrenheit. Found by Henning.

- The praying mantis is the only species with one ear. It has one giant ear located deep in the centre of its thorax. Found by Zoe.

- Over recent years, insect footsteps have got quieter. Found by Zoe.

Henning Wehn - Words

- The word "mafia" never appears in The Godfather films, despite appearing constantly in the original novels. Producer Al Ruddy removed all mentions of "mafia" and "cosa nostra" due to pressure by the Italian-American Civil Rights League, a pressure group set up Joseph Colombo, the head of a minor New York crime family, to improve the image of mobsters and deny the existence of the mafia. Found by Holly.

Zoe Lyons - Parties

- The phrase: "There is a party in my pants and you're all invited", comes from a tradition where boys would have a party when given their first pair of long trousers. Called "breaching parties", they were common in Britain between the 16th and early 20th centuries in well-off families. In early childhood, boys and girls dressed alike at first, until the boy came of age and was given their trousers. Found by Holly.

- In 1694, Admiral Edward Russell had a punch bowl so large that it had to be attended by staff rowing around inside it in canoes. It was actually a fountain in Alicante. The staff worked in 15 minute shifts to avoid passing out from the fumes. Found by Richard.
