Silly Putty Recipes: Two Easy Methods for Homemade Fun
Get ready to relive those iconic childhood moments! Remember pressing your putty onto newspaper comics, bouncing it across the kitchen floor, or stretching it into impossibly thin sheets? Now, you can replicate that experience with just a few common household items. You can even use small cookie cutters to create fun shapes and designs in your putty for added play.
While the classic silly putty often comes in pink, your homemade version doesn’t have to be limited to a single shade. You can literally make it any color of the rainbow! Imagine a batch of green putty for a nature theme, vibrant blue for a winter wonderland, or a mix of colors for a festive birthday party. The possibilities for customization are truly endless, allowing you to match any decor or theme you can dream up.

Essential Safety Precautions for DIY Putty
Before diving into any DIY project, especially those involving children, safety should always be your top priority. Parental supervision is absolutely essential for all ages, and certain ingredients, like Borax, require careful handling by adults only. We strongly advise you to read our full safety disclosure before beginning this or any other craft project. Once the silly putty is completely finished and safe to handle, children can then enjoy hours of creative play under supervision.
Always ensure that hands are thoroughly washed with soap and water after playing with silly putty, and especially before eating or touching eyes. This practice helps maintain good hygiene and prevents any accidental ingestion of small particles. By following these simple guidelines, you can ensure a fun and safe crafting experience for everyone.

Silly Putty Ingredients: Choose Your Recipe!
We’re providing two popular methods for making homemade silly putty: one using liquid starch and another using Borax. It’s important to note that liquid starch often contains Borax, so parental handling of all ingredients is crucial for both methods. However, if you opt for the Borax solution (Instructions #2), the dramatic transformation from liquid to solid is particularly captivating to watch and a fantastic science lesson for kids!
Engaging in science experiments with children is always a rewarding experience. Even when adults handle the potentially hazardous ingredients, kids can observe firsthand how different elements combine and change states. This not only sparks their curiosity but also ignites an excitement for learning more about the world around them.
Recipe Method #1: Liquid Starch Silly Putty
This method is remarkably similar to making many versions of slime, so if your kids are seasoned slime creators, they’ll pick this up quickly! It’s a great introduction to the world of polymers.
- 1/4 cup liquid starch (ensure it’s the laundry type, not cornstarch)
- 1/4 cup white school glue (like Elmer’s glue)
- Optional: Food coloring for custom colors
Instructions for Liquid Starch Putty:
- In a mixing bowl, combine the liquid starch and white glue. Stir the mixture together thoroughly. If you’re using blue liquid starch (which is common), your putty will naturally have a blue tint unless you add food coloring.
- Continue mixing until the ingredients begin to come together and form a cohesive ball.
- If the putty feels too sticky or wet, add just a tiny touch more liquid starch and continue to mix and knead. Repeat this process gradually until the desired non-tacky consistency is achieved.
Just like with slime, you can easily adjust the texture of your silly putty. Add a little more starch to make it firmer and less sticky, or a touch more glue to make it stretchier and softer. Experiment to find your perfect consistency!
Recipe Method #2: Borax Solution Silly Putty
This method offers a slightly different tactile experience and a clearer demonstration of the chemical reaction.
- 1 bottle (typically 4 oz or 118 ml) white school glue
- 2 cups hot water
- 1 tablespoon Borax (sodium borate)
- Optional: Food coloring for custom colors
Instructions for Borax Putty:
- Parental Supervision Required: In a separate bowl, carefully place 1 tablespoon of Borax. Absolutely do not allow children to handle Borax directly. Revisit our safety disclaimer for important guidelines on conducting experiments with children.
- Add 2 cups of hot water to the bowl with the Borax. Stir vigorously until the Borax is completely dissolved.
- Let the Borax solution sit for a few minutes until it becomes mostly clear again. This indicates that the Borax has fully integrated with the water.
- In a third bowl, if desired, mix your white school glue with a few drops of food coloring. Be cautious not to add too much food coloring, as excessive amounts can sometimes make the putty too loose or prevent it from fully absorbing, potentially staining hands longer than desired. For a classic look, leaving it the natural opaque color is often best.

How to Make Silly Putty: Bringing It All Together
Now for the magical part! If you’re using the Borax method (Instructions #2), carefully hold the bowl containing your colored glue (or plain glue) above the bowl with the clear Borax-water mixture. Slowly and steadily drizzle the glue into the Borax solution. You’ll immediately notice the glue starting to coagulate and form a small, wiggly pile or mass within the water, as shown in the image above. This is the exciting chemical reaction taking place!
- Once the glue has formed a discernible mass, reach into the bowl and carefully pick up the glue pile. Don’t worry if it feels a bit slimy at first; that’s normal.
- Begin to knead the substance vigorously in your hands. This kneading process is crucial as it helps to squeeze out any excess water and fully integrate the ingredients. Continue kneading until the putty becomes less sticky, more elastic, and forms a smooth, cohesive silly putty substance. The more you knead, the better the final texture will be.
- Now your homemade silly putty is ready for play! Get creative with its classic abilities:
- Image Transfer: Press the putty firmly onto a picture from a newspaper or a pencil drawing. Peel it off, and then press it onto a clean sheet of paper to transfer the image!
- Shape Creation: Use small cookie cutters to create fun shapes directly in your putty, or mold it into various figures and objects.
- Bouncing Fun: Form your putty into a ball and watch it bounce! Experiment with different sizes for varied bounce heights.
- Stress Relief: Simply squishing and stretching the putty can be incredibly therapeutic and a great way to relieve stress.
Does Silly Putty Dry Out? Essential Storage Tips
Unlike store-bought silly putty, which is often oil-based and can remain pliable for a surprisingly long time even when left uncovered, homemade silly putty typically behaves more like slime. This means it is more susceptible to drying out and hardening if exposed to air for too long. To ensure your creations last, proper storage is key.
Always store your homemade silly putty in an airtight container or a sealed plastic bag. Freezer bags work exceptionally well because you can press out all the excess air, creating a tighter seal than many containers. Small plastic Easter eggs or other lidded containers are also excellent options for keeping individual portions fresh and ready for play. Storing it correctly will significantly extend its lifespan, allowing for many more sessions of creative fun.
How to Get Silly Putty out of Clothes and Fabric
Accidents happen, especially when kids are involved in messy, creative play. If your homemade silly putty finds its way onto clothes, carpet, or other fabric, don’t panic! There are several effective methods you can try for removal. Always test any cleaning method on an inconspicuous area of the fabric first to ensure it doesn’t cause damage or discoloration.
Here are some tried-and-true tips:
- Hand Sanitizer Method: Apply a small amount of clear, alcohol-based hand sanitizer directly onto the silly putty stain. Gently rub the area; the alcohol can help dissolve the putty. Once dissolved, blot the area with a clean cloth.
- Freezing Method: Place ice cubes directly onto the silly putty until it freezes and hardens. Once frozen, you can often scrape off the brittle putty with a dull butter knife or the edge of a credit card.
- Dish Soap Treatment: For any remaining residue or discoloration, rub a small amount of liquid dish soap (like Dawn) onto the stain. The degreasing properties of dish soap can help break down any oils or binders in the putty.
- Wash as Normal: After attempting these removal methods, launder the garment as you normally would, using your preferred detergent and water temperature. Check the stain before drying, as drying can set any remaining residue. If necessary, repeat the cleaning process.
With a little patience and the right technique, you can often save your garments from those sticky situations!
