Need help on presentation for PE?

In PE class, we have to make up an original sport. In my group, we created a game called Insane Angry Birdies. It uses badminton rackets and is kind of like soccer, but on a basketball court. My teacher is very strict and we have to have a really good grabber in the beginning. Any ideas to keep the audience from falling asleep? BTW, the presentation can only be 3 MINUTES MAX!
