If you want to create your own TED Talk, you only have to follow these six steps

1) Have a vague goal, you don’t have time for details;

2) Distract the audience with a non-tangential demonstration;

3) Provide a link to your idea with the latest buzzwords in science;

4) About mid-way give an inspired rhetorical question;

5) Your breathless climax should be a double down on the rhetoric;

6) Finish off with the implication that your audience is what really makes it all possible. How does this work? Here is an example talk:

1. Vague goal: You want to cure illiteracy while restoring wonder to the world.
2. Non-tangential demonstration: You perform a magic trick you learned once as a child.
3. Tenuous scientific link: You claim that the ball that disappeared from your hand and was pulled from an audience member’s ear actually represents the quantum foam.
4. Inspired rhetorical question: “What if instead of one ball, there were a thousand? Or a million? Or one ball for every illiterate child in the world?”
5. Breathless climax: “Okay now imagine two.”
6. Finale: “This just goes to show that many large groups of passionate people with unlimited resources can make magic happen.” Bow to thunderous applause. Exit juggling.
