Color Changing Silly Putty Recipe

Silly Putty has been a popular toy for decades, captivating kids and adults alike with its fun, bouncy, stretchy, and squishy properties.

But imagine taking this beloved substance to the next level by making it color-changing! Color-changing Silly Putty adds an exciting twist to a classic toy, making it not only more fun to play with but also an intriguing science experiment.

In this detailed guide, we’ll walk you through the steps of making your own color-changing Silly Putty, along with the science behind it, tips for a smoother experience, and much more!

Materials You’ll Need

Before you dive into the fun of making color-changing Silly Putty, let’s gather the materials. You’ll need the following items:

• White school glue (such as Elmer’s Glue): This is the base ingredient for making your putty.
• Boron solution (Borax dissolved in water): This chemical is what gives your putty its stretchy consistency.
• Thermochromic pigment powder: This is the star ingredient that will make your putty change color based on temperature. You can find this online or at craft stores.
• Food coloring (optional): If you want to add an extra dimension to your putty’s color, use food coloring.
• Cornstarch or baby powder: To keep your hands clean and prevent the putty from sticking to everything.
• Warm water: To dissolve the Borax in.
• A mixing bowl: To combine all the ingredients.
• A spoon or spatula: To mix the ingredients.
• A storage container: To keep your putty fresh when you’re done.

Step-by-Step Color Changing Silly Putty Recipe

Now that you have everything you need, it’s time to create your own magical color-changing putty!

Step 1: Prepare the Borax Solution

The first step in creating your Silly Putty is to prepare a Borax solution. This will act as the activator for the glue, giving your putty its stretchy and elastic qualities.

Start by mixing 1 teaspoon of Borax with 1 cup of warm water in a bowl. Stir the mixture thoroughly until the Borax is completely dissolved.
Set the solution aside for later use.

Step 2: Prepare the Glue Base

In a separate bowl, pour out about 1/2 cup of white glue. This will be the foundation of your putty.

If you want to add extra color to your putty, this is the time to add a few drops of food coloring. Stir it well so the color is evenly distributed throughout the glue. You can get creative with your colors here! Purple, green, or blue would work great with the thermochromic pigment.

Add the thermochromic pigment powder to the glue. The more pigment you add, the more pronounced the color-changing effect will be. Start with 1/2 teaspoon and adjust from there.

Stir thoroughly until the pigment is well incorporated.

Step 3: Mix the Glue with the Borax Solution

Now, it’s time to combine the glue base with the Borax solution.

Slowly pour the Borax solution into the glue mixture, stirring constantly. You’ll start to see the putty form right away!

Keep stirring until the putty comes together and starts pulling away from the sides of the bowl. If it’s too sticky, add a little more Borax solution, a few drops at a time.

Once the mixture has formed into a solid mass, remove it from the bowl and knead it with your hands to make it smoother and more pliable. The kneading process is essential for activating the putty’s stretchy properties.

Step 4: Let Your Putty Cool and Set

After kneading the putty for a few minutes, it’s time to let it cool and set. The cooling process will help the putty firm up a bit, making it easier to handle and play with.

Store your putty in an airtight container to keep it from drying out. It will stay fresh and stretchy for several weeks if kept in a sealed container.

Test out your color-changing putty by holding it in your hand and watching how it reacts to the warmth of your hands. You should see the color shift as the putty warms up.

Tips for the Best Color Changing Silly Putty

Experiment with Different Colors: Try mixing multiple colors of thermochromic pigment for unique effects. You can even create a gradient effect by mixing pigments of different temperatures (such as a warm color like red and a cool color like blue).

Be Patient with Kneading: Kneading the putty well will help to evenly distribute the pigment and make it stretchier.

Use Small Amounts of Borax: Be cautious with how much Borax you add to the mixture. Too much can cause the putty to become stiff and crumbly, which isn’t ideal for play.

Protect Your Hands: If you’re using multiple colors or pigments, wear gloves to avoid staining your hands.

Store Properly: Keep your color-changing Silly Putty in a sealed container when not in use to ensure it stays fresh and doesn’t dry out.

Conclusion

Making your own color-changing Silly Putty is a rewarding project that combines creativity, science, and hands-on fun.

Not only do you get to enjoy the satisfying stretch and bounce of Silly Putty, but you also get to explore the science of temperature and chemical reactions.

Whether you’re doing it as a fun activity with kids, as a solo craft project, or as a way to learn about materials science, color-changing Silly Putty is sure to provide hours of entertainment.
