I think you use diet coke so it will go further. It's lighter.
My only complaint was the Disturbed song. I mean, it's a little hyperbolic for what they were doing. It's not like they were mixing their own black powder rocket. Or riding a mountain bike. Y'know, doing something really cool. All they were doing was making a mess with soda. That's not really getting down with the sickness, in my opinion.
But, looks like fun. I think it'd be a good idea to use this on the next climb Killa. I want video. And put two mentos in there. Don't be cheap.
