How To Fix Slime That Didn’t Work Out

Slime gone wrong

I’m crazy about slime and slime recipes. We make a ton of it at our house and as you can imagine, sometimes the slime recipe goes wrong and we find ourselves wondering just how to fix slime that didn’t work out. Slime, in particular, seems to cause people a lot of trouble and I’m here to help. So for those of you looking into how to fix slime that didn’t work out, look no further. Simply follow my instructions and if you want individualized attention just email me with pictures of your slime woes and I will send you a fix that’s specific to your specific problems. My email address is shootingstarsanlittletoycars@gmail.com.

So first thing’s first – the slime recipe that I decided to troubleshoot is the one that uses clear glue (aka PVA) and liquid starch (Sta Flo) since it seems to be the one that causes the most trouble for folks.  (If you are using our laundry detergent recipe, you can follow this same set of directions.  Keep in mind that the laundry detergent is a direct substitute for liquid starch.)  The first interesting thing I learned is that over time the liquid starch will settle.  This was leading to a lot of inconsistency in and of itself.  So the first thing I learned about this slime recipe is:
 
Always shake your liquid starch container a bit to make sure that it is well-mixed.
 
Now that you’ve shaken your liquid starch, let’s look at the two ways this slime can go wrong.
 
First way:  Not enough liquid starch
 
How do you know if this is your issue?  Your slime will be stringy – it will stick to your fingers a ton.  As you stir, you’ll see little strings of glue grabbing your spoon.  If you grab a section of your slime, it won’t lift out in a glob – just a small stringy portion will stretch up.
 
The solution to this problem is to add more liquid starch, approximately one Tablespoon at a time.  Stir well to mix in between each addition of liquid starch.  You’ll know you’ve added enough when you no longer see those strings of glue grabbing your spoon as you stir, and you’ll be able to lift all or most of the slime out if you grab a section of it.  After a few minutes of kneading it will be just right and certainly not sticky. A slime that’s had too much liquid starch added will be stringy, but NOT sticky.  It won’t stick to your fingers – it will slide right off.  It won’t stick to a spoon or even to itself.  It’s just gross looking clumps of goo ( we’re talking seriously SUPER gross here).  You can see strands of floating slime, and there will be standing liquid starch.
 
How do you fix it?  First, pour off any standing liquid starch.  Then add clear glue approximately 1/4 cup at a time and stir.  Once the slime starts holding together, you will need to knead it by hand.  After adding glue and kneading for 2-3 minutes, it will be just like new!  It will gel even more cohesive if left overnight in a sealed bag.
 
So what does perfect slime look like?  It holds together and doesn’t have any strings of glue or standing liquid starch. If you grab it, it moves as one cohesive unit. 
 
Kneading it for a minute or two will make it smoother and help it form into a more cohesive unit.
 
Because we’ve noticed that the amount of liquid starch needed varies wildly from slime to slime (depending a ton on what you add to it – food coloring, liquid watercolors, glitter, etc), I really recommend adding whatever amount of glue you’d like (we usually make a slime batch with two bottles of clear glue, but even one bottle makes a decent amount of slime) to a container and then slowly adding liquid starch – about 1 Tablespoon at a time – and stirring between each addition until you have slime that looks amooth and well blended with no bubbles.
 
Once you’ve made your slime, be sure to knead it for a few minutes to make it uniform (honestly, you can just hand it to your kid to play and that will mix it for you!).  Store it in an airtight container or Ziploc bag when you aren’t using it.  It will keep for several weeks. And don’t worry if it bubbles.  That’s normal.
 
I also found that vinegar will dissolve this slime – just in case you get any on your carpet or clothing!
 
I hope this helps those of you who have had slimes backfire on you in the past!
