Uses for large styrofoam blocks include insulation and plant drainage. Though highly flammable and not recommended for residential use, styrofoam is ideal for insulating tool sheds and pump houses. Gardeners sometimes use it for plant beds or boxes. Styrofoam blocks can be cut up into smaller pieces for protective shipping.
The material can be used in an assortment of craft and art projects. It is possible to cut styrofoam to create miniature buildings and holiday ornaments. Because it is light and it floats, styrofoam covered with a quick-drying fabric makes bath toys or bath pillows. Anglers can use it as floaters or as a means of storage for hooks and lures.
