Today we are making a super easy Gak recipe, aka gack slime. This fun homemade slime recipe with only 2 ingredients is great for kids of all ages. Homemade Gak is a fun alternative to slime — it’s thicker, squishier, and makes fun sounds when you press down into it.

How to Make Gak
If you were around in the 90s, you probably had Gak as a toy or watched the Gak attacks on Nickelodeon which included a green slime substance being dumped most likely on someone’s head.

Two-Ingredient Gak Recipe
Supplies Needed to Make Gak
- 1 bottle clear school glue
- 3/4 cup liquid starch
- Optional: food coloring
Directions to Make Gak
Step 1
Add the glue to a bowl. If you want to color the gak, add a few drops of food coloring and mix it into the glue.
Step 2
Slowly stir in the liquid starch, adding 1/4 cup at a time.

Step 3
You’ll need to use your hands to incorporate the liquid starch into the glue. It’s kind of like kneading bread — just keep working it until it’s fully incorporated.

Step 4
Let it sit for a few minutes and it will acquire a smooth consistency.

Finished Gak Slime
Then, it’s ready for play!

We had a lot of fun stretching out the gak.
It’s really cool how it will melt back down into itself if you let it sit long enough.
