I've been in the Middle East/Southwest Asia for the past 40 months, and every can of soda that I have had from here [I would assume they come from the UAE] has a pull tab. Apparently, they haven't caught on to the latest aluminum can technology. That led me to thinking back to my junior high/high school/college days where someone always seemed to be collecting these tabs for charity. 50 pull tabs could pay for an hour of kidney dialysis - or something like that. There were never any monetary donations that were asked for - just pull tabs. I always wondered what the heck you could do with a pull tab. Now, I ask this question to the collective intelligence of the HTF - What's the story with those damn pull tabs? Was/Is this some sort of scam? Do people still ask for these - or has modern aluminum can technology made this obsolete?
