Peal a potato in ONE shot?

Well, you've gotta face the fact that there is a way to peal a potato in one shot and right now I'm going to tell you how!
1. Pick a nice-looking potato and turn the knive you're using 360 degrees around the potato. ( don't slice too deep only slice the skin)
2. Put the potato in hot water for at least a few minutes
3. Put the potato in icy-cold water and count to 10
4. Take the potato out and hold both sides of the potato
5. Using a quarter of your strenght squish both sides.....Finish! Out comes a perfect potato without skin. ( This miraculous experiment can work if you are careful enough not to cut too deep into the potato as said in No.1)
