Chicken Socks Foam Book
This may look like a 7 1/2-inch-square book, but don't be fooled by appearances. Inside, it's a million miles wide (roughly the size of a young imagination). It comes with a bunch of foam shapes and a glue stick -- all the tools you need to build anything you want.
A tip-of-the-iceberg example: Glue a few shapes on a piece of paper and make apples, airplanes, alligators, arrows, aardvarks and absolutely anything else. Each page is filled with inspirational artwork that can be copied exactly or cheerfully ignored.
Either way, the book works brilliantly -- a fenceless playground for boundless imaginations. Comes with over 200 pieces of brightly colored foam and a glue stick. For ages 4 and up.
