My speech was on Why hotspot isn't always reliable. Hotspot is used in cricket and it is designed to register if a cricket ball has hit the bat on its way through to the wicket-keeper. I thought I did quite well. I was afraid that my topic wasn't very interesting but it raised some very good questions. I was very proud of what I wrote but I wasn't very well prepared. All in all I enjoyed this and needed to work on my presentation a bit more.
