Slime may be a hobby for others, but for our family, it’s a passion. We’ve tried over 100 slime recipes, and we’ve tried just about every variation there is, from classic borax slime to baking soda slime. Along the way, we’ve found the tricks and tips that  will work to make sure your slime comes out right every time you make it. I’ve made a free printable slime troubleshooting guide for you so that you’ll never have a slime fail again!

Follow along with these tips and tricks and don’t forget to download your slime troubleshooting guide that also contains our favorite slime recipe to take with you the next time you want to make slime.

SLIME TROUBLESHOOTING GUIDE: MAKE PERFECT SLIME EVERY TIME!

So, you want to make slime. So you get some glue, and you get some borax or laundry starch, you mix it up, and bam!

A gloppy mess.

What’s a person to do?

Follow along with this handy slime troubleshooting guide and you’ll never have a slime fail again.

WHY SLIME?

Slime has fascinated individuals for an entire generation. Today’s slime is a bit less messy than the old slime you would see on TV, but there hasn’t been a year since 1990 that slime hasn’t been popular with the kiddos. We make slime regularly as a sensory experience for our kiddos, and also as a science lesson. Slime is a great example of polymer bonds, and almost acts as a non-Newtonian fluid with some recipes. We like to use slime to test the scientific process, to learn about chemical bonds, and to have fun with something squishy.

WHY SLIME FAILS

Slime can be a tricky beast before you get the hang of it. But slime usually fails for one of three reasons:

  1. You used the wrong ingredients. We have the best luck with Elmer’s glue and Sta-flo laundry starch.
  2. You didn’t follow the recipe. Ratios are incredibly important for slime. We usually use a 1-1-1 ratio with water, starch, and glue.
  3. Your ingredients failed. Sometimes, a batch of glue or starch won’t be mixed right, and that can cause slime to fail.

FIXING COMMON SLIME ISSUES

Too Runny

You probably used the wrong kind of glue or didn’t put in enough starch or borax. Add more and keep mixing.

Too Goopy

You may have put in too much starch or borax. You might be able to fix this by adding more glue or water, but this is the hardest problem to fix, and you might have to throw the slime out.

Too Stringy

You may not have kneaded the slime enough. I’ve found that letting it rest for about 2 minutes then kneading again helps fix any stringy problems.
