Check out this three minute talk which I gave at Famelab 2016 Swiss-Semi final in Basel.
This talk was aimed for non-scientific audience therefore the main challenge was to make them understand the process of bioirrigation and its ecological significance without using scientific terms. In this talk, I used general terms to describe the overall process of bioirrigation with the help of prop (long and short ropes). I received an amazing response from the audience which was evident from their lots of questions, and interaction after the talk.
"I received the highest number of audience votes, and was awarded Audience Prize". :)
Hope this would help viewers in preparing their scientific talks for the non-scientific audience!
