Rash facts. 1  Rash is not a specific diagnosis. Instead it refers to any sort of skin inflammation and/or discoloration that distorts the skin's normal appearance. 2  Common rashes include eczema, poison ivy, hives, and athlete's foot. 3  Infections that cause rashes may be fungal, bacterial, parasitic, or viral.
Many of us use the term Styrofoam as a reference to most plastic foam packaging. We include foam drinking cups, packaging peanuts and the white material that our appliances, toys and so many other items are packaged in. In fact, most of this is not Styrofoam.
Use a craft knife to cut Styrofoam. A craft knife is ideal for cutting small, thin pieces of foam, but is not recommended for pieces with a thickness of more than 1 inch (2.54 cm). Unlike serrated blades that tear through foam, the sharp blades in craft knives tend to flatten or compress the Styrofoam.
