Yo that's epic. I want a viral video like that

Looks like your campaign is struggling. I think your goal is very high. Is that the minimum amount you need?
I think it comes down to studying the conversion funnel. Are your fans going to be interested in the actual project? Are you "selling" it? Have you actually asked those people you've helped to pledge or just kind of hinted at it?
I've seen some popular people get pledges just based on the force of their personality. However, most projects need a strong marketing/positioning element. Not saying yours doesn't but you gotta nail down why your fans aren't converting into backers.
