The joke growing up was that my brother didn’t know how to climb a tree until we moved into a house with a mulberry tree. And there we found him, 15 feet off the ground munching on plump, delicious mulberries.
I remember every summer our sidewalks, our cars, and our windshields would be stained a purple-ish color because of an abundance of berries. So when we discovered a small purple mulberry tree in our backyard, it was the perfect opportunity to make a naturally dyed slime with berries!
How to make slime dyed with berries
The easiest way to make squishy, fail-proof slime is by using typical Elmer’s glue, liquid starch, and some water.
Mix together 1/2 cup of water and 1/2 cup of white PVC glue until it is smooth. Then slowly add 1/4 cup of liquid starch. It will almost instantly start clotting into a mashable, smashable slime.

Once it’s pliable and stretchy, you can knead in some berries. We personally chose mulberries because we have purple mulberry trees in our neighborhood and it encouraged out kids to get outside and into nature to make their slime.

But to help kids learn even more from making berry dyed slime, you can pick up an assortment of fruit at your local produce section.
“What do you think will happen if we mix raspberry and blueberry together?”
“How do you think the color of the slime will change if we add blackberry to the white slime?”
“If you mix white berries into white PVC slime, will it change colors?”
We even added more white glue to Jenn’s ball of slime to see exactly how it would change both the consistency and the color of her naturally dyed slime.

What happened is that it got less viscous and started moving and dripping a lot more quickly… which became a fun game of “dont’ drop the slime.” And then a not so fun game of “mom, help me!!!!!” 🤣
