Slime, Ooblek, Gak, Flubber, Silly Putty – it’s been called all that. I’d always wanted to make this. The way the goo oozes in your hand is just so irresistible.

But I found that I wasn’t going to get the most important ingredient here in Singapore – Borax, which is a laundry compound people elsewhere can find in department stores and it’s just not available in Singapore. So when I looked for alternatives, I found that liquid starch can do the trick too (But the liquid starch should have borax as ingredient). And that is difficult to find too. What I did find in our department stores is this.

Note: This post has 2 recipes, one with Easy on starch spray and other with Epsom Salt. If Easy on starch spray is not available to you, click here to jump to the Epsom Salt recipe.

Method 1: Using Easy On Starch Spray

Gather and add your ingredients:

  1. Washable School Glue (clear or white)
  2. Food Colour – colour of your choice (green is good because it’s more popular and if you have a Ninja Turtles fan in the house)
  3. Starch Spray (you need to be careful while using the pressurised bottle since it was not designed to be used as liquid. It mists a lot while spraying and works well in some particular angle so this step is not advisable for a child)
  4. Sprayed starch will froth like in the picture 4 above. Stir everything together.

Now comes the fun part, messy one too. Leave the stirrer and start kneading with your fingers.

If it looks like the first picture above, you need more starch and more kneading… until it looks like the second picture above and it no longer sticks to your fingers.

To make the slime stretchy and playable, you must knead it longer. But what better way than to let the kids do the kneading playing?

While they are at it, you might make some monsters, let the slime ooze through your fingers or just watch the slimy goodness stretch towards the floor like it’s got a life on it’s own. Alien Goo!

It is super stretchy and you just can’t keep your hands off it. And I have absolutely no idea why hubby can’t find this fun!

Method 2: If you don’t have borax or liquid starch

I like this method because it’s perfectly safe, even for a young child to use. Epsom Salts are naturally found, is good on the skin (use it in baths for a relaxing experience) and the pack I got from Guardian pharmacy is food grade. The consistency of goo made is very different from the starch spray slime. It’s not as stretchy and doesn’t really ooze so I’d much rather call it a silly putty than slime.

How to make Silly Putty using Epsom Salts

Gather and add your ingredients:

  1. Equal parts of Epsom salts and warm water: Add in a bowl and stir. Epsom salts take time dissolving in water. Using warm water makes it dissolve faster but has no effect on the consistency of the putty.
  2. Food Colouring
  3. Glue: Add as much or as little putty as you want to make. It’s better to start with smaller portions just to try at first. You’ll be able to reuse your salt solution to make further batches of putty by just adding desired amount of glue.

  4. Stir very lightly. When it looks like the first picture above (mucous like consistency. GROSS, I know!), you might want to use your fingers to check if the glue is still sticky (picture 2).
  5. When it doesn’t stick to your fingers anymore, remove from salt solution and knead in another bowl. Soon, your putty should look like picture 3.
  6. Continue to knead and play with it.

The Epsom Salt Silly Putty is very silky and smooth. it’s not as stretchy as the Borax substitute but since it holds it’s shape much longer it’s better for some kinds of play (especially for people who do not like the way slime oozes).

If it doesn’t workout for you:

If your putty looks like the above pictures, it means you stirred it too long in the salt solution. The glue keeps reacting with the Epsom Salt solution as long as it’s together. So if it lumps up like this, you may still be able to knead it and make shapes for a while it will soon dry out to the consistency of dried glue. So be alert and remove the gross looking mixture from the solution as soon as it doesn’t stick anymore. It will thicken to the right consistency when you knead it enough.

Storage

Both of these recipes need to be stored in refrigerator in between playtime to save it from drying out. The Epsom salt recipe dries faster.

Other Options

If you don’t find even Epsom Salts in your country or you’d much rather not use any of these recipes and are looking for something more eco friendly, or safer for toddlers, you might want to checkout my Oobleck (corn starch slime) recipe.

    1. I doubt the glue pen would work. Worth trying if you’re making a very small amount of slime. But not for playable amounts..

  1. Thank you for this article. It helps me a lot in preparing a lesson for my Kindergarteners. I just hope I can find the ingredients at Fairprice.

  2. Hello, I came across your post on making slime without borax. My question is, what is the Elmer’s glue you used? Is that like any PVA glue or…? I used some white glue purchased at Daiso and it just came out in a lump and won’t mix with the salt solution at all.

    I’d appreciate your help, thank you.

    1. Elmer’s is a brand of school glue. I believe it is just a PVA glue. The reason I’m using Elmer’s is, I purchase most of my art class supplies from Art Friend store and get enough stock of clear and school glue bottles when they have it.
      As for the slime, it doesn’t have to mix with the salt solution. The slime will be formed when you mix glue in the solution and you’ll have to remove it as soon as it is not sticky anymore like I mentioned in the post. Hope this helps.

    1. Hi Saedah, I get Elmer’s glue from ArtFriend stores. They tend to go out of stock often, so I usually stock up on supplies.
