one hundred

100 degrees centigrade = boiling point
100 pennies = one dollar
100 years old = letter from the Queen
100 Is = C
100 centimetres = 1 metre (thanks jimchmst! ;) )
100 acre wood = my dream home as a child

So many fun things surrounding the number 100.
Hopefully I'll explore a bit more in my next 100 blips!
