Keep kneading!Īfter 5-10 minutes of kneading, our putty is firm, stretches easily and is ready for action. After a couple of minutes, it is still softer than we’re after. For the best results, use non-washable glue. Silly putty is stretchy, bouncy, and fun, and it’s super easy to make To start, measure out about 1/2 cup (120 ml 4 fl oz) of school glue into a medium-sized plastic bowl. The putty will become less slick and will become firmer the longer it is kneaded. Pour 4 oz (120 ml 4 fl oz) of non-washable school glue into a bowl. Knead the putty until it becomes firm and pliant. Remove the putty from the remaining starch and pat with a paper towel to remove excess starch. As soon as the glue “stands up” (as shown), stop stirring and let the mix rest 3-4 minutes to allow the starch to completely permeate the thickening glue. The consistency will soon become rubbery. Once the color is even, add ½ cup of liquid starch and stir. Choose any color and add as much as needed to reach the desired effect (we used 20 drops of purple here). Pour ½ cup Elmer’s Glue-All into a glass or plastic container.Īdd food coloring to the glue and stir using a craft stick. Ready to give homemade putty a try? It takes just a few minutes, and older kids will have no trouble making their own with adult supervision. This magic has something to do with the glue’s properties as a liquid polymer causing molecules to strand together when introduced to the liquid starch. This stuff bounces, it stretches, it lifts pictures out of the funny papers and it doesn’t stick to clothes. By combining Elmer’s glue and liquid starch, we enjoyed a revelation similar to that of James Wright. When a friend passed along a recipe she had found for a homemade version, I was intrigued. Thus, nutty putty was born and within a few years became the “must have” toy of the 1950’s. Although it didn’t turn out to be the rubber substitute he had hoped for, as a novelty it was a great success. It bounced high, stretched far and melted only at high temperatures. In an attempt to create a viable synthetic rubber, engineer James Wright combined boric acid and silicone oil and discovered the results had interesting properties. Plus, it only has two ingredients (three if you want to color your silly putty). It’s borax-free and doesn’t contain any white glue. But the story of this classic toy starts during World War II, when rubber shortages were profound. This DIY putty recipe is even easier than most. What is nutty putty anyway? You may know it best as Crayola’s Silly Putty. This week we tried our hand at a new craft for kids (and adults, too!): homemade nutty putty. Still, we managed to find a good time in our usual DIY fashion. Much as I’d prefer to be outside soaking up what’s left of summer, rain seems to be the standard forecast these days. A few weeks ago, we turned a rainy day into a pretty good time by making our own play dough.
