If you remember, the phone's charger got broken somehow, and we'll just assume Nancy's phone has a different kind of charger. You'll need to find or make a new charger --
-- and in this instance, you'll have to make one, oy! But it's really a lot easier than you think (and a lot easier than it would be in real life, I'm thinking). Read to the end of this hint for step-by-step directions.
There's a book in the main house that will give you all kinds of help here -- go down the hall and turn left under the stairs to find the tool room.
The book on the work bench is called, "Electricity Manual For Making Batteries With Common Household Items." Man, isn't that a coincidence!
The book has a number of different schemes; the one you want is on page 4, the one labeled "Fruit."
You need nails, pennies, citrus fruit, and wires with clips on the end. It's all in the house here, if you know where to look.
The wires with clips are in a jar on the same worktable with the battery book. Leave them there till you have all the rest of the stuff.
You can find a basket full of oranges in the parlor, on the table with the tea makings next to the door.
There's a jar full of pennies in a jar in the workshop; look on the table in the middle of the room with the toppled movie projector.
Nails are also in the tool room, though they're kind of hard to see --
-- look at the wall to the left of the worktable where you found the electricity manual. You'll need a hammer to pull the nails out of the wall, and you can find one on the porch. (Walk up to the porch swing, then turn around and see the red-handled hammer on the column at the left.)
Assembling the battery is easy, once you have all the parts. Put the oranges on the table; add the nails and then the pennies; then click on the wires in the jar. All done!
