an interesting opening and closing for presentation on energy drinks?

[BhumiPatel]

I am doing a presentation on the affects of energy drinks for my communications class. My presentation is supposed to be five minutes long and my audience consists of students ages 18-22 and my professor. I want some ideas for interesting opening and closings to have a good impact on my audience and professor. I want something bold, unconventional and thought provoking! Some of the ideas i can use are

any related videos
an interesting fact
a story
an enactment
interaction with the audience
also to help, my three main points for the presentation are:

rise of energy drinks in the market and their ingredients
affects of energy drinks on our body
alternatives to energy drinks

thank you so much!
