The 10 Greatest Inventions of all time

Recently my daughter was writing an essay where she had to write about which was in her opinion the greatest invention of all time. I was clueless. And that's when I decided to think about it and come up with an answer. I wasn't able to come up with 1. Instead I came up with the 10 that I consider to be the greatest inventions of all times.
