How to Make Galaxy Slime
Since we’ve been studying the night sky at our cooperative preschool, the twins have been talking about it quite a bit at home. They especially love talking about stars, so I showed them some artist’s renderings of the Milky Way galaxy that I found in one of my reference books. As we were admiring the swirls of color, a lightbulb went on in my head, and the idea for Galaxy Slime was born!
Making the slime was pretty easy after I figured out the nuances. Yes, there are nuances to slime making- I’m as surprised as you are
ANYWAY, to make our cosmic slime we built upon the tried and true recipe of equal parts Sta-Flo Liquid Starch
and Elmer’s Clear School Glue
.
I wanted our slime to consist of several galaxy colors so I could swirl
them into a big spiral for the invitation, so I made smaller batches of
black, turquoise, violet, and white/silver using the following
proportions (I used the recipe below for each different color):- 1 bottle of Elmer’s Clear School Glue
- 1/2-3/4 cup Sta-Flo Liquid Starch
- Liquid watercolors
(several squirts until you get the desired color)
- Fine glitter in a variety of colors
So here’s the skinny on slime-making…you
gotta take it slow. The first time I tried it, I just dumped all the
ingredients into a bowl at once and started mixing. After 20 minutes and
really sore wrists, it was pretty obvious it wasn’t coming together, so
it went into the trash. So I tried again, but this time I followed a
different progression. You’ll want to put your glue into a bowl first.
Then add your coloring (I used liquid watercolors but I’ve heard that
food coloring works, too) and glitter and mix well. THEN you can start
adding your starch, but just add it in small increments at a time,
stirring well to mix after each one to incorporate your starch fully.
After the first couple of additions you’ll need to use your hands to
knead the starch in, just like you are making bread dough. Another
thing- I know the common wisdom is equal parts starch and glue, but I
never needed the entire amount of starch. When I did use the entire 3/4
cup of starch, the dough become more like a gak and wasn’t as stretchy
as I wanted. So, just add a little at a time and do a “stretch test”
after each increment is kneaded in. Once your slime is the consistency
you prefer, STOP!
If you are a regular reader of Twodaloo,
you know I love presenting sensory play in fun ways. I decided to spiral
our colors together on top of our mirrored tray from Ikea to suggest a
sparkly galaxy. I thought it looked pretty inviting, and sure enough,
the twins wasted no time jumping right in! My son in particular enjoyed
this material- something almost as stretchy and active as he is!
He was completely enthralled with the texture. He wanted to feel it with his hands, his arms, his feet…everything.
Both of the twins were very fascinated with the stretching. And this slime has plenty of streeeeetch!
It’s funny- typically with sensory
materials the kids love to add loose parts and/or “guys” (little
figures) to engage in some pretend play, but they weren’t interested
when it came to the slime. They were just content with exploring it on a
purely sensorial level.
Even after all the colors were mixed together, the slime remained beautifully colored and inviting.
I mean, have you ever SEEN a more gorgeous
slime bubble? Seriously. Also, “gorgeous slime bubble” is not a phrase I
would ever have predicted would be in my lexicon. Just sayin’.
Don’t worry- more on those slime bubbles
coming tomorrow. While Will was busy cheesing for photos, Syd was up to
her elbows in her own little project, and I can’t wait to share it with
you! (Click HERE to read how we tweaked this recipe to make GIANT REUSABLE BUBBLES!!)
*A note about safety: This post
was originally titled “Borax-Free Galaxy Slime.” Many people search for
alternatives to traditional slime recipes that use Borax because there
is lots of debate about its safety in play recipes…if you do your
research Borax is really a mild irritant that is only harmful if
ingested in large quantities (just like salt or starch or glue would
be). Many people confuse borax with boric acid, resulting in lots of
confusion and misinformation. HOWEVER, after a little more research I
discovered that Sta-Flo does contain a very small amount of sodium
tetraborate (borax) so I have changed the title so not to be misleading.
Sta-Flo is classified as non-hazardous but can cause stomach
upset/vomiting if ingested in large quantities (again, just like glue or
starch), so no matter what you use to make slime (Sta-Flo or pure
Borax), it’s definitely not for eating and children should be supervised
during play. Use common sense- if your kids are still tasting sensory
mediums, save this until they are older! It’s up to you to decide what
recipes you are comfortable using for play!
