There is something satisfying about playing with silly putty. When I was young, I remember spending hours molding, squishing, and stretching the little balls of silly putty. whenever I had a spare dollar, I always spent it on new silly putty.
My kids share a similar obsession with silly putty and slime so it’s only natural that we make our own DIY silly putty. I’ve stumbled across dozens of silly putty and slime recipes and we’ve been slowly making them all. You can find quite a few varieties here at Living Well Mom too.
The beauty of making your own DIY silly putty is it’s super easy to make and much cheaper than buying it premade from the store!
A note on the texture: Due to the ingredients, the final texture of this silly putty will be similar to an oobleck rather than the kind of silly putty you purchase in the store. The cornstarch keeps the putty from sticking to your fingers, but the texture will be a bit doughy.
This DIY silly putty is even easier than most, as it only has two ingredients (three if you want to color your silly putty).
Within about 30 seconds, you will have satisfying silly putty that will keep your kids entertained for quite a while.
How to Make DIY Silly Putty:
What You’ll Need:
- 1 cup of cornstarch
- 1/2-1 cup clear gel-like soap
*
- Food coloring or gel colors
- A small bowl and spoon for mixing
An important note on the soap: Certain types of liquid soap will NOT work for this silly putty. Clear, gel-like soaps or soaps that have the consistency of hair gel or conditioner will work the best.
We used Method Gel Hand Soap for the silly putty in these photos and I’ve also used Target brand strawberry shampoo with good results.
We also used gel food coloring and had no issues with dye sticking to our hands when the project was over.
Let’s get started.
Dump your cornstarch and soap into your bowl and mix up.
If you want, add a couple drops of food coloring.
I recommend that you start out with a smaller amount and add a little more until you get the color you (or more likely) your children want. Don’t add a ton of food color at first to your silly putty or you may end up with stained hands.
You really only need a little bit of color to dye your DIY silly putty. The more coloring you add, the deeper your color will be.
Mix the ingredients together with the spoon until it is too hard to mix, then use your fingers.
We found that we could mix using a spoon until our mixture turned into crumbles, and after that, we had to mix using our hands.
You may need to adjust the amount of soap used depending on the humidity of your room. It was dry in our house, so we used almost a full cup of soap.
If you make this silly putty during the hot summer months, you may not need as much soap.
When your silly putty is moldable and still a bit slimy, but no longer sticks to your fingers, it is ready to go!
My girls were very excited about playing with this DIY silly putty and they fought over who got to play with it first.
Eventually, I broke the silly putty into two pieces and let each of them have one.
The girls were fascinated by how the silly putty kept its shape like play dough, but only for a little while. Within a few seconds, the silly putty would lose its shape and become a single blob.
Our silly putty did start to dry out quickly. As it dried, it would become flaky. Adding another pump of soap to the putty moistened it up again and made it playable. You can keep adding soap until you are done playing for the day!
This DIY silly putty project is simple enough for older kids to make and quick enough to please little kids, too!
DIY Silly Putty Troubleshooting Tips:
Certain types of soap are not suited to this activity. Clear, gel-like soaps do best. You’ll have best results with soap that has the consistency of hair gel or conditioner.
Due to the ingredients, the final texture of this silly putty will be similar to an oobleck rather than the kind of silly putty you purchase in the store. The cornstarch keeps the putty from sticking to your fingers, but the texture will be a bit doughy.
Humidity and the brand of your individual ingredients can alter how much of each ingredient you need.
If your silly putty is too runny: Keep adding cornstarch one tablespoon at a time until your mixture stiffens.
If your silly putty is too crumbly: Add a bit more soap until the putty can stretch again.

PinIngredients
1 cup of cornstarch
1/2–1 cup clear liquid soap (Method hand soap works best
Food coloring or gel colors
A small bowl and spoon for mixing

When your silly putty is moldable and a bit slimy, but no longer sticks to your fingers, it’s ready!
Notes
- Clear, gel-like soaps or soaps that have the consistency of hair gel or conditioner will work the best. We have used Method Gel Hand Soap and Target brand strawberry shampoo with good results.
- This putty will dry out as your children play with it. Add another pump or more of soap to it to bring it to the desired consistency.
- This silly putty doesn’t store well, but we’ve had some luck storing it for a couple of days in a sealed ziploc bag. Your results may vary, particularly depending upon the air humidity.
diane says
we made something similar with conditioner and it came out smelling heavenly. I bet your kids had fun with this!
Isabel says
So instead of using the dish soap you used conditioner?
Tylar says
Yes you could it would work just as well
Anne Osolinski says
how much conditioner would you use….I have a playgroup that I would like to try the recipe on and there are about
18 children……
Tylar says
You would use 1/2 a cup each batch
James says
Hi my name is James and this recipe is a huge mess . I had my daughter do this because she has adhd and so I thought is was a good idea and it wasn’t the recipe failed
Amanda says
Mine did too.. did you ever figure out what went wrong, or it’s just a bad recipe? My kids really want to make putty but they did not like this… in the picture their hands are clean but that was not my experience.
Crystal says
That sounds like fun! I appreciate the lack of Borax. I’ve never got any of that on hand, and prefer activities that don’t require special purchases.
Neil says
I am the same simple and easy that’s
How I think of thing and no money
Ready when i want it actually i mean the little ones
Izzy says
Borax is hard to work with
Madi says
Me to
Sarah says
Omg, this looks so fun! i want to try it with my kids, i bet they will love it.
Amber Edwards says
I have a special needs daughter who will love this! It is perfect for her sensory play! I love how easy it is to make!
Jennifer says
I used to play with silly putty all the time when I was a kid. I can’t think of any kid who wouldn’t love to help make this and then play with it.
codruta says
mine is very sticky to the fingers, I dont know why, i tried to put more cornstarch, then more dish soap
Brenda P says
Hi Codruta, The humidity of your room can make a HUGE difference in how sticky it is. I would suggest keeping adding corn starch a little at a time until it is the right consistency. You’ll know it’s right when it can form into a ball and feels just a bit dry to the touch.
Georgia Davies says
add about 2 tsp of cornstarch and 1tsp of dish soap it works then
Monica says
Can some one make my kids one I just can’t seem to do it right I tried like 6 times and. Omg nothing my kids were exited and then they started crying
Erika says
Hi Monica, I’m sorry you’re having issues with this activity. If you could tell us what’s happening, we might be able to better assist you. 🙂
mads says
my daughter tried this and it turned out like play-dough, i guess it kinda worked
Christa says
This recipe did not work for me at all. I used Dawn dish soap and cornstarch. When more dry, it left powdery clumps or just residue on my fingers. Adding more soap made it sticky. I gave up.
Brenda P says
Hi Christa,
We used a clear-blue hand soap for our experiment. Dawn soap might be too runny for this activity. At first, the putty will be quite sticky. At that point, we added a bit more cornstarch until it was just pliable enough to not stick to the fingers, but not so much that it dried out. Hope this helps!
izzy says
Can a earth dishsoap work we only have organic
Chloe Lamb says
hello I am not mother nor a frequent user of this site but i have discovered it in search of a recipe for silly putty. This recipe was outstanding and I was very pleased wit the outcome of my putty. although things did go as planned (such as a jeans mishap) everything is well now. God is good
Martha says
Can this be kept for use another day?
Erika says
Yes, you can store it in a ziploc baggie. 🙂
Reve shmaysani says
Can we do this with flour instead of cornstarch plz reply fast
Erika says
No, you need cornstarch. Flour is different and won’t have the same results.
Megan says
I used dawn dish soap and it did not turn out well at all. Has anyone tried with regular hand soap like dial and gotten good results?
Megan says
If you are using the blue dawn dish soap, let it settle a bit dusted in cornstarch if it is sticky. I did that thinking it wasn’t working, had to tend to my baby, and came back 5 minutes later. It had slowly let gravity form it a little more. I mixed it with my hands maybe 5 times and it started to form the putty just right.
Erika says
Thanks for sharing this great tip, Megan!
Deborah Armstrong says
Thanks for sharing this recipe for silly puddy. My youngest grandson is starting to ask about doing projects like this and I can’t wait until he comes for a visit so I can make this with him! Thanks again!!!
Madi says
Worked great I added sparkles to it and it looks great.A little sticky but a really good recipe
Lena says
Can I do it also with normaly food starch?
Super DIY!
Elle says
Anybody tried it with potato or tapioca starch? My daughter is allergic to corn
Sam says
Can you use cornflour instead of cornstarch or are they the same thing?
Erika says
Cornflour is very different and wouldn’t work – the texture is very different. If you have tapioca flour or arrowroot flour, one of those may work. I haven’t tried it however they both have similar textures to cornstarch. (Though cornstarch is cheaper to buy)
Tammy Dulaney says
This was an awesome experiment for the day! I had to add a little extra soap. I used Baby soap and the kids love it! Then we pinched off a tiny piece and washed our hands with it!!!? How long will this keep?
Kaylee says
OMG this is amazing
