Given the brand’s track record, when Cadbury Schweppes has said in the past that it was going to support Snapple, we’ve all scoffed a bit.

But not this time. The company is buying Snapple a Super-Bowl ad, and is praying for a tight game, as it’s for the fourth quarter.

Both Cadbury Schweppes and the Coca-Cola Co. are running ads, trying to horn in on longtime Super Bowl sponsor PepsiCo.

The ad shows how quickly an additive can catch fire. In promoting Snapple’s new Green Tea line, a young man searches the globe for the EGCG – the very same tea compound that Coke put forth three months ago as the key element to raising the human metabolic rate and burning calories in its own new tea, Enviga.
