I once blocked our sink from far too much rice in various bowls. Couldn't shift it, so bought a 'compressed air' unblocker - basically a can and a rubber cup. Press button and 'boom' clears the block. Loads of fun, but I guess if the plumbing is a bit old it could blow seals out.
"Boom" might be a bit much for the complicated plumbing under our kitchen sink. Could end up with a "yer only supposed to blow the blahdy doors off!" situation.
I haven't bought shampoo in the 5 years I've been here, so that shower bottle cap had been stuck in the drain for at least 5 years!
