The funny thing is that when I first got Tide Pods, my wife would cut them open with a knife, pour the liquid in the machine, and throw the rest away. It took some time to convince her to throw the ENTIRE pod in the machine because she was certain the solid part was plastic that doesn’t dissolve.
I’ve actually seen remnants of the outer shell still intact after a wash cycle was completed though. Can’t stand these things and have a bunch that are sort of melted together. Screw it, maybe I’ll take part in the Tide POD challenge and start eating.
