So my wife buys a new plastic shower curtain that employs embedded magnets to hold it snug to the tub. She takes a shower and tells me she thinks she put it up backward because the magnets aren't holding it firmly to the tub. Sure enough when I take a shower I see these weak little suckers don't hold the curtain to the tub at all but there's no difference between the thickness of the magnet pocket and the curtain and they're both made from the same material.
Now comes the good part:
I tell her the material is too inflexible for such weak magnets and that's why they don't hold well. I also ask her why she thinks she put it up backward. She replied "Don't be silly. Everyone knows that magnets pull on one side and push on the other"! I then explained that that's only true where two mating magnets are concerned. I further elaborated and explained how unlike poles attract and like poles repel.
Her reply:
"Well if that's true then please explain why refrigerator magnets only hold on one side"?
I explained that the refrigerator magnets are separated from the refrigerator by only about 5 thousandths of an inch on the back side. While the magnet surface is separated from the front side, where those clever notes, pictures and what-not are visible, by about 160 thousandths of an inch.
I'm not sure but I don't think she believes me and she will probably reverse the shower curtain anyway!
