Plastic bottle caps for cancer? another urban myth?

Signs around are office are asking us to keep plastic pop bottle caps for cancer treatment.
It sounds a lot like the aluminum beer tabs for dialysis Urban legend - though you can save the tabs and give them the Ronald McDonald house.

Anyway, i checked Snoopes.com and got nada. Anyone know if this is Bullshit or not?
My hunch is it is, but this is the second person trying to collect caps for cancer.

 

Ask where the bottle caps are going.

 

I don't know one way or the other, but what would be the motivation to keep them otherwise? What can you gain from the caps? Are these people like the underpants gnomes? "Step 1: Collect underpants. Step 3: Profit."

 

begs to differ:

 

A quick check of My Coke Rewards shows that it takes 4000 points for a digital picture frame, 6100 for a darts cabinet and 13,250 for a 19" HDTV. No listing for a chemo session.

 

We always collected those tabs in elementary school and middle school for the same reason. Maybe they recycle them for cash?

 

1,350?
Shit, i need to drink me a shitload more Coke...

 

Sorry, it's a five-digit number. At 1350 I would be putting myself into a high fructose coma, because then it would actually be within reach.

 

aluminum yes.
Plastic?

 

Exectly, throw the can away but keep the tab. We want to recycle the tab for cash.

 

Next to the recycling can in our break room is an old plastic bottle half full of can tabs. I'm convinced the damn thing has been there 10 years and the cancer patient/book program/animal shelter it was intended to benefit has long since bit the bullet. Still, I throw my can tabs in because I'm determined to fill the bottle and see what happens.

 

Like a two-liter plastic bottle? A water cooler bottle? A carboy?
