Diet Coke + Mentos=Unclogged drain?

Yeah, it effectively releases all the dissolved carbon-dioxide (the stuff that makes fizz).

I’m sure the force isn’t trivial (it could very well explode a soda bottle), but I doubt it would compromise a sink. Either the clog will clear or it will come back out of the drain before that occurs.
