Galaxy Slime

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
(5 oz)
- 1/2-3/4 cup Sta-Flo Liquid Starch
(I found mine at Walmart)
- 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 got to 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! Even after all the colors were mixed together, the slime remained beautifully colored and inviting.
