The Potato Paradox

You have 100 pounds of potatoes and you know that they’re made up of 99% water. You leave them out overnight and they dry out a bit, so they’re only 98% water. How much do they weigh now? 99lbs? 98lbs? They’ve only lost 1%...

Nope. 50 pounds -- they’ve lost half their weight! But how? Bust out your burlap potato sack, because Kevin is about to do the dirty work of uncovering the answer to a bizarre veridical paradox that just doesn’t seem to add up. Gravy not included.

    Go tell someone that salad is 5% away from being soup.

    Next time I get asked if I want "soup or salad" I might have an existential crisis...
  • Jesus can walk on water, I can walk on Lettuce, Lettuce is 95% water, I am 95% Jesus
  • @tiny021085
    Easier way to explain this. 100lbs and 1% is solid matter. So that's 1lb solid matter. They dry out and now it's 2% solid matter. But still only 1lb. And if 1lb is 2% of the total weight, then the total weight must be 50lb. You don't even have to do the water % math this way to get the same result.

    Kevin : "You must hug your potatoes to show that you care" [3:26] As a person who has gone to Ireland for vacation twice, I can confirm this is why the potatoes there are so high quality
  • @londonerdanny
    I feel like he's explaining two separate concepts. First is :- What would be left after 1% evaporates? Removing 1% of 100 lb which would leave almost 99 lb. [Depending if it were by weight or by volume] Second is:- Doubling the solid content from 1% to 2% which would equate to removing 50% of the water content. Those are two separate things.
