A fresh layer of sticky snow offers kids even more opportunities for building the playscapes of their imaginations than a sandy stretch of beach. Unlike sand sculptures, which are prone to collapse--and subject to flash floods--packed snow holds its shape and can last for weeks.

To help your child build his dream city, use a shovel to build a mound of snow. Then, with mittened hands, he can shape miniature skyscrapers, bridges and parks. If the snow isn't damp enough to pack well, use a spray bottle filled with water to moisten it.

Use the edge of a metal spatula to smooth walls, slope roofs and square up corners. It's also a handy tool for plowing the city's roads and walkways. Hollow out windows, doorways and tunnels with a large serving spoon.

For a glitzy effect, your child can use food coloring mixed with water to spray-paint the completed city. He can even populate his creation with a bunch of mini snowmen and pets or line the streets with tiny snow cars. Afterward, take a picture to send to relatives.
