"Blankie, let's use the magnet to find the nut!"
"But how, Marty?"
"It's simple! Do you know what the nut is made of?"
"Iron?"
"That's right! And what does the magnet attract?"
"Iron!... Now I get it! We'll pull the magnet over the leaves and it will attract the nut."
"That's the plan, Blankie."
Even Marty is surprised at how quickly they find the small part.
