Years ago I decided that I would try "free cryo" on a power cord (had 3 of the same model).
The instructions were to seal it in a plastic bag and freeze it for 24 hours, then remove it from the bag and let it set out for a day, or so.
I forgot about it and found the cord approx. 3 months later (pushed to the back of the fridge) with the plastic bag breached.
Let it set for a few days, plugged it into my DAC (Bel Canto 1) and found that it made my setup sound like a small portable transistor radio.
I then submerged both ends in a bowl of raw rice and came back to it a week later (still sounded the same).
Cut the ends off, tossed them, and saved the cable which was eventually used to snake our new @ the time water saving toilet.
I then tossed the cable.
It was one of the first Absolute power cords (sold on A’Gon) for $30/each.
I still have the other two, plus a third one I found @ a local thrift.

PS:
Around that same time placed a photo of myself in a plastic bag and then into the freezer, but now don't recall what the purpose of doing so was.
I take the photo out for viewing from time to time (this is over a 20 year time span) and am still amazed that to this day I have not aged one bit.
