Just by putting the potato in hot water first, and letting it boil a bit, and then immersing the potato in ice water, you can get the peel to come right off. I bet some of those sailors who were comdemned to peel potatoes for their wrongdone deeds would have loved to know about this tip.
And it is a bit deceiving because it only works after you prep it and boil it for 5 minutes, not to metion the 10 seconds you take cooling it or the 30 seconds it takes to make the bowl of ice water...
You could just get a sharp peeler and go to town on it, but it is interesting to see.
The guy's voice is a bit funny too, don't you think? Not sure what that's about.
