100 things we didn't know this time last year

This is sort of a fun list. A few of the 100...

  • The collective noun for rhinos is "crash".

  • The Sydney Harbour Bridge contains just 16 nuts and bolts. The rest is held together by rivets, because it doesn't need to be dismantled.

  • Herrings break wind to communicate and keep the school together.

  • A "jiffy" is 10 milliseconds in computer science terms.
