7. CREATE A SPY NETWORK.
Few concepts capture a kid’s imagination more than secret messages, which is what compelled Coy Bowles, guitarist with the Zac Brown Band, to fashion a game out of a quirk in his house’s design. “We have a 4-inchtall pipe that connects one recording-studio room to another,” he says. “Its purpose is to pass cables through the wall, but my daughter and I now use it for fun.” Bowles and his budding spy swap messages and toys through it. “It’s cute to see her so curious about what’s happening on the other side of the wall.” No pipe? Hide messages anywhere: in drawers, behind bookshelves, in the vegetable crisper, inside a favorite book.
