Looking for a fun activity that will keep your kids busy for hours? This DIY Silly Putty recipe takes less than 5 minutes to make and kids LOVE squeezing, pulling, stretching, and playing with their very own putty! Plus it only requires 2 common household ingredients (NO borax) and is so so EASY to make!

Scale

Ingredients

1 cup of cornstarch
1/21 cup clear liquid soap (Method hand soap works best*
Food coloring or gel colors
A small bowl and spoon for mixing


Instructions

Add the cornstarch and 1/2 cup liquid soap (use the lesser amount to start with) into a medium-sized bowl and mix.

Add a couple drops of food coloring and mix. Add a little more color if desired (you shouldn’t need a lot.)

Mix the ingredients together with the spoon until it is too hard to mix, then use your fingers.

Add more soap if it’s dry. Low humidity in the air will cause you to need more soap.

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.
