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.

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.

3 Simple Ingredients = Wildly fun bath time!

Three Crafty Girls Where Have You Been?

Then a friend sent me this video of three cute sisters calling themselves Three Crafty Girls. In the video they quickly and easily make this crazy, big, fluffy slime. The best part? The basics of their recipe were so simple. You could find them anywhere.

Where were these girls during my years of slime failures????

I was so excited. I raced down to my corner store, grabbed the one ingredient I didn’t have and within 5 minutes of getting home had my first successful batch of slime!

After that batch, we made 10 more. Each time playing with the recipe and technique, fine tuning it until it was so simple, so easy.

Slime That Is Soooooo Stretchy!

This slime is so stretchy my kids were able to stretch a single batch over 40 feet through my house before it finally broke!

How To Make Slime – So Easy and So Quick

You need three ingredients:

White Elmers School Glue (non-toxic, washable)
Baking Soda (known as bicarbonate soda in some places)
Buffered Saline Solution – You can find this in the eye care aisle. Make sure it is the buffered saline. In the States this will contain boric acid, but the one I bought here in Canada doesn’t have boric acid or sodium borate listed in the ingredients. It still worked though! Formulas may vary based on your location. Check the ingredients and ensure it is buffered saline, and it should work.
Optional – food coloring

Add a bottle of white glue to a bowl (I found this quite forgiving so just try and get most of the glue out of your bottle or if you buy in bulk estimate the portion). Sprinkle with 1/4 teaspoon of baking soda. Mix completely with a spoon. Add a few drops of food coloring if you want at this point and mix it in completely.

Now, start adding a few drops of the buffered saline and mixing with the spoon. Just do it a few drops at a time. It will start pulling together immediately. Continue adding a few drops, then mixing. Repeat until it starts to pull into a stringy ball.

This next bit is how we find it works the best, put some buffered saline on your hands. Pick up the slime and start kneading and mixing it with your hands. It will be sticky, but only through working it will you get the best, stretchy slime. Work it really well. It will change into a better slime consistency as you work it.

If it is still sticky after a few minutes of kneading, add one or two drops of buffered saline. Continue working it in. Don’t add too much or you will start to lose the stretchy properties and become more prone to breaking. If you find your slime is breaking you are adding too much saline.

Voila! SLIME!

Playing with slime is a lot of fun, but, like any activity, parents need to be involved and informed. Please, read all labels. I can only speak to the products I can buy locally. The formulas and products in your area may have different ingredients or formulas which may produce different results. Extreme caution should be used if you are substituting any ingredients. Be informed and use appropriate safety steps. If you have any questions or concerns, speak to your doctor or local health practitioner.

It takes about 5 minutes to make the slime, so I’ve set the video to double time. Enjoy!
