Store the homemade silly putty in a zip top baggie. Stir with a spoon and then knead with hands as the mixture thickens.Pour the borax mixture into the glue and water.Mix 1 teaspoon borax with ½ cup warm water in the measuring cup.Of course, adding a bit of food coloring makes it fun too. Pour the water into the mixing bowl and stir until smooth. DIY Fall Sensory Bins 2 Ingredients Fake Snow How to Make Puffy Paint with Sand Silly Putty Ingredients You can simply mix these two ingedients together and get some putty fun. Fill the empty glue bottle with water and shake the bottle. Empty the bottle of glue into the mixing bowl.You can make your own Silly Putty at home-or at least something similar. Bounce the ball on the same surface and from the same height as before and note how high it bounces.ĭoes temperature affect how high the Silly Putty ball bounces?.Put that same ball into the freezer for an hour.Roll Silly Putty into a ball and bounce it on a flat surface.Do this easy experiment to see how temperature changes how the Silly Putty ball bounces. The properties of Silly Putty change with the temperature. When Silly Putty is rolled into a ball, it bounces when dropped on a smooth surface just like a rubber ball. However, when the putty is pulled apart rapidly, the hydrogen bonds break apart abruptly and the putty breaks. When the Silly Putty is stretched carefully, the hydrogen bonds break apart slowly and allow the putty to hold together. These bonds make the Silly Putty easy to roll into a ball and stick to itself. Silly Putty is made of polymers, or long chains of molecules, that are cross-linked by weak hydrogen bonds. It wasn’t until it was packaged in Easter eggs for the upcoming holiday and marketed as a children’s toy, Silly Putty, that the popularity of this accidental material took off. Scientists tried to discover a practical application for this new substance, but could not. It could bounce, stretch, break, and flow. This new polymer was a non-newtonian fluid, meaning that it acted as both a viscous liquid and an elastic solid. The result was a new polymer with some peculiar properties. One of those engineers accidentally dropped boric acid into silicone oil. Silly Putty Historyĭuring WWII, there was a rubber shortage, so scientists and engineers were hard at work trying to create new polymers and substances that could take the place of rubber. Add Dish SoapĪdd 1-2 tablespoons of dishwashing liquid to the bowl containing the cornstarch.Silly Putty is one of those classic toys that never gets old. The bowl doesn’t need to be very big as this recipe doesn’t make a whole lot of putty… just enough for one child to play with! 2. Start by pouring ¼ cup of cornstarch into a bowl. Stir until the Borax is mostly dissolved. In a large glass measuring cup or a bowl combine 1/8 of the water and 1 tablespoon of Borax. Add in 4 to 6 drops of the food coloring and stir. But this recipe worked great when I used a cheap brand of dish soap from the dollar store, so that’s what I’ll be using whenever the kids ask for this! Step-by-Step Instructions 1. In a bowl, mix 1/4 cup water and 1/4 cup glue until it is well combined. Note: Funnily enough, the only brand of dish soap that I haven’t been able to make this work with is Dawn-perhaps because it’s too concentrated and the water content isn’t high enough? I just ended up with sticky play dough instead of silly putty. You can also use clear dish soap and add a drop of food colouring or liquid watercolour paint. I used clear dish soap to create white putty, but if you choose coloured dish soap, your silly putty will take on its colour. The colour of your DIY silly putty will depend on the colour of the dish soap you use. Dish soap (you can use Dawn or any other brand you happen to find).Cornstarch (also called “corn flour” in Australia and the U.K.).That’s why I was so thrilled when I found out that you can make silly putty at home using nothing but dish soap and cornstarch-without harsh chemicals like glue, borax or liquid starch.Īnd while I wouldn’t recommend letting your kids put this silly putty in their mouth, I like how much safer it is and how much softer it is on the skin compared to traditional slime! And lately, with things being so busy, I’ve really been on the lookout for sensory recipes that are quick to make. I’ve been known to prepare lots of taste-safe and edible sensory activities, but I do like to switch things up and try new recipes. And although I always use contact lens solution as a slime activator rather than borax or liquid starch, it’s still a bit harsh on the skin and I’m not comfortable giving it to my toddlers. The trouble with slime, though, is that it’s not safe for young kids, especially ones who like to put things in their mouth. To be totally honest, I think I may even enjoy it more than the kids do. But from the first time I made it, I was hooked. It seemed like such a weird idea, and I was a bit hesitant to try it. I never understood what the slime craze what about… until I tried making it for my kids.
