How to make homemade slime

Years of Slime Failures

Have you ever seen a really cool slime recipe?

Over the past couple of years I’ve been so inspired by some of the amazing slime activities I’ve stumbled across. Yet, when I tried to make my own slime, every attempt was a complete and utter failure.

About six months ago I went on a massive shopping trip buying every possible ingredient. I had researched the science, read so many recipes. I was determined to make slime.

But after spending over 6 hours trying, all I had was a lot of wasted materials, batches of nasty, unusable gooey substances, and a splitting headache (that powdered borax always does a number on me!).

To say I was frustrated with slime making would be the understatement of the century. I put together a lot of our lessons learned and tips on slime here.

Slime safety and tips. Everything from understanding ingredients (and how they vary) to tips about soap residue. What you need to know about slime.

When looking up a slime recipe, one of the first things I noticed was that almost all of them called for liquid starch. As a Canadian I don’t have access to liquid starch. To demonstrate my own devotion to the slime cause, I even tried making my own liquid starch using a technique from an older military man, turned prepper. It still didn’t work!

Next I turned my attention to trying it with borax powder. Failure.

Plus the Canadian government advises against using borax powder around children, and I have lung and heart conditions that borax powder aggravates. So I ditched that idea pretty quickly.

I spent hours reading labels and searching for the one, rare brand of detergent that I was promised would work. It still failed. Probably because the exact magical laundry detergent I was told to find, couldn’t be found anywhere, and the others were poor substitutes.

It shouldn’t have been so hard. All I needed was a substance that would give the glue some stiffness and remove the stickiness. There had to be another answer. Finally I found it.

Basic Slime Recipe Variation 3: Crunchy Slime

This slime is hard to resist pulling apart and watching all colorful beads disperse. Note: The dye from the beads will slightly color the slime so there is no need for extra color.

Slime Tips and Tricks

  • Lotion commotion If you have slime that breaks apart when you stretch it, add lotion a few squirts at a time and knead to combine. Be careful though, too much and your slime will become a stretchy mess.
  • Temperature matters! Temperature really affects viscosity (read about it here ) and depending on how warm or cold it is where you are making slime, you may see some differences in your slime. On hot days I usually use less starch and on colder days I might need a little more.
  • Movement matters too. If you move your hands too slowly while handling slime it tends to stick to your fingers. If you move your hands quickly and handle the slime like pizza dough it tends to behave more like a solid. This is because slime is a non-Newtonian fluid. Read about it here.
  • How to refresh your slime. As slime sits in a container it does settle and get more gooey. Refresh it by removing it from the container and kneading it between your hands for few minutes.
  • It’s on my clothes! Got slime everywhere and now you are panicking? Don’t worry. Slime is easily dissolved by white vinegar. I recommend having some on hand at all times when playing with and making slime.
  • Contain the mess. The best way to contain slime messes is to use a large tray. I love these from IKEA. Having a defined work area helps to keep kids slime in one place.
  • Storage Most slime will last indefinitely if stored in an airtight container. That said, I’ve found some moldy slime around our house. The best way to prevent mold from forming is to keep the container tightly closed and to make sure your hands are clean before you make slime so you are not unwittingly adding in something that will cause mold to grow.
  • Best Slime Containers Want to know what the best slime containers are? I buy these deli containers from our local restaurant supply store in bulk. They are fairly inexpensive, stack well, and are airtight!
