Homemade Silly Putty Recipe Using Borax

Time for a little homemade Silly Putty!  I am sharing this little activity with a warning that a 4yr old may not quite be old enough to actually play with this stuff without making a HUGE mess and even having to soak in the tub a few times in order to remove it from hair and eyebrows 😉   This one also got me in trouble with the husband when he found a big glob on the carpet in the office – oops!

That being said – we decided this weekend to try out making homemade Silly Putty – it actually turned out a little more like Flarp or slime but it still ended up being great fun for the kids to play with.

What you will need

Homemade Silly Putty Recipe (with Borax) – Pin it!!!

  • 1 Bottle of School Glue (I picked up the Crazy Art brand at Walmart for $0.36 ea)
  • Borax
  • Food Coloring
  • Water


Start out by emptying the bottle of glue into a bowl.  Fill the glue bottle about halfway back up with warm water and shake to get any glue off the sides and then pour into the bowl.

Slowly add the Borax/Water mixture to the glue.   At first it will look like curdled milk after a few minutes it starts to get a more elastic look/texture.  It will start getting very difficult to mix, at that point go ahead and take it out of the bowl (it WILL be sticky) and start to work it with your hands.  The more you kneed it and squeeze with the more it will dry and firm up.


If your mixture is not firming up or is still super sticky then you can add some more Borax/water mixture and continue to kneed it and it will eventually get there.


In the end you will have some super elastic putty – we found 2 reusable Gladware container to store it in.  The girls played with it ALL weekend!  And even though my little one made a disastrous mess with hers, it was not really a big deal because this stuff cleans up super easy with just a little warm water. 

If you cannot find Borax at your Walmart or Target (I could not find it at mine) then try a smaller grocery store. I found it at Food City and the big box was $3.99.  Arm & Hammer also has a Super Washing Soda which is the same thing if you can find that.
