@uber: I’ve heard the same thing, but we made it into a paste and kept it on our tongues for almost a minute. From what I understand that’s as close to the actual fruit you can get. :)
It was fun, but it didn’t live up to the hype. I only got through about half a lemon before it started to make my tongue feel raw and I began to taste the sourness again.
Great pomegranate link, btw. The day I learned that was the best day of my life…err, maybe just the summer.
