I was cleaning the keys of my PC keyboard in a bowl containing a mixture of water and Dawn liquid soap.
When I poured the dirty water into my bathroom sink, one of the keys went down the drain and the key is in the P-trap.
I cannot remove the P-trap nor the tailpiece. The top of the tailpiece is 8 inches above the bottom of the P-trap.
How can I retrieve the key out of the P-trap?
