Inspire your kids to perfect their sculpting skills with this cheap and easy activity that takes a little planning and some freezer space. Put water in an assortment of containers with different shapes – plastic cups and bowls, empty milk jugs, a muffin tin, some ice-cube trays. (Dollar stores often carry ice molds that come in different shapes). Kids can add food coloring and plastic figurines for pizzazz. When everything is good and frozen, watch them turn their ice blocks into sculptures and towers. They’ll have fun getting wet during the building – and melting.
