How to Make Floam

How to Make Floam Floam  is a slimy substance with polystyrene beads in it that kids can mold into shapes. You can sculpt with it or use it to coat other objects. You can store it to reuse it or allow it to dry if you want permanent creations. Its a lot of fun, but not always easy to locate. You might be able to buy it at some stores and online, but you can make a type of Floam yourself. As with slime, its very safe, though anything containing food coloring can stain surfaces. Dont eat Floam. Polystyrene beads simply arent food. How to Make Floam Difficulty: Easy Time Required: This is a quick project: It takes only minutes Supplies 2 tsp. borax1/2 cup water1/4 cup white glue (such as Elmers)1/4 cup waterFood coloringA resealable plastic bag1 1/3 cups polystyrene beads Steps Dissolve 2 teaspoons of  borax completely in 1/2 cup (4 ounces) of water. Two teaspoons of borax will produce a stiff product. If you want more flexible Floam, try 1 teaspoon of borax instead.In a separate container, mix 1/4 cup (2 ounces) of white glue and 1/4 cup of water. Stir in food coloring.Pour the glue solution and the polystyrene beads into a plastic bag. Add the borax solution and knead it until its well mixed. Use 1 tablespoon of the borax solution for a very fluid Floam, 3 tablespoons for average Floam, and the entire amount for stiff Floam.To keep your Floam, store it in a sealed bag in the refrigerator to discourage mold. Otherwise, you can allow it to dry into whatever shape you choose. Tips for Success How it works: The borax reacts to crosslink the polyvinyl acetate molecules in the glue. This forms a flexible polymer.If you use a 4-percent solution of polyvinyl alcohol instead of glue, you will get a more transparent product that will hold shapes better.You can find polystyrene beads at craft stores, usually as fillers for bean bags or dolls. You can grind plastic foam cups using a cheese grater if you like.
