Four Fun Facts


Four fun facts for you:


canned foodTinned Food
: Tinned food was invented in 1810, but for the next 48 years people who wanted to eat it had to use a hammer and chisel. The can opener wasn’t invented until 1858. Doh!

screwdriver and screwsScrewdriver: The screwdriver was actually invented 100 years BEFORE the screw. Originally, it was used to extract nails. (I wonder when its name changed from “nail extractor” to “screw driver” then??)

 

markingMarking: The invention of “marking” was in 1792. It was by a Cambridge University Chemistry tutor called William Farish. (Before this, exams were taken orally and by practical demonstrations in universities. Gee, thanks Mr Farish!)

 

mr whippyMr Whippy: The team behind the invention of Mr Whippy ice-cream included Britain’s first female Prime Minister, Margaret Thatcher. (Ironic that she became known as the “milk-snatcher” after she oversaw the removal of free milk to primary schoolchildren in the 1970s when ice-cream’s primary ingredient is….milk)

  1. Great post, Pam. All this information is very interesting. I am glad I do not have to open cans with hammer and chisel! Sometimes it’s difficult enough to do it with a can opener. 🙂
