How to Make Jello Slime
Materials:
- Sugar free Jello
- Cornstarch
- Warm water
Equipment:
Instructions:
Step 1: Find what you need
- Gather your supplies and materials.
Step 2: Combine the ingredients in a bowl
- Pour a package of sugar free Jello into a bowl.
- Add 1/2 cup of cornstarch.
- Stir or whisk the 2 ingredients together.
- Add 3 Tablespoons of warm water.
- Stir until you can’t anymore.
Step 3: Mix with your hands and add more water
- Use your hands to mix the ingredients, creating a sandy textured mixture.
- Now you’ll need to add more water, a tiny bit at a time. We recommend adding 1 teaspoon at a time at first.
- Continuing adding bits of water until the mixture comes together and you can knead it in your hands.Make sure you knead the mixture well in-between adding water, as it can get too wet and sticky quite quickly.
- The slime is ready when it’s smooth and stretches, instead of breaks. At the end you’ll need to add water just a few drops at a time.
- Your Jello slime is complete!
- Then wait a few hours (or add a bit less water initially) and use this recipe to make Jello playdough! You can roll it out, shape it, and even use cookie cutters.
Helpful Tips:
- This slime is taste-safe, meaning it’s okay for younger kids (who might put things in their mouth) to play with. Keep in mind that while raw cornstarch is okay to eat in small amounts, eating a larger portion of the slime can cause digestive upset.
- The slime dough should be smooth, stretchy, and not too sticky. Keep adding a few drops of water at a time until you reach this consistency. If you make it too wet, add a bit more cornstarch.
- Once the Jello slime sits for a bit, it’ll become more like playdough. You can roll it out, press cookie cutters into the dough, and mold shapes!
Does Jello slime stain your hands?
Playing with the slime shouldn’t stain your hands too badly, but mixing the pink/red Jello with your hands definitely does (though it also makes them smell delicious!).
Within a few hands washes the colour will fade away, and we found that sugar free Jello stained a lot less than regular Jello.
Can I use regular Jello to make Jello slime?
Yes, you can use regular Jello, but we had more luck getting a slime texture with the sugar free Jello.
Regular Jello is a lot more sticky and it didn’t work quite as well for us. It does, however, make a great Jello playdough recipe.
What texture does Jello slime have?
Jello slime is a little bit like regular slime, but it’s closer to a stretchy playdough texture. It definitely has some slimey-ness to it, but you have to be pretty precise in the combination of water and cornstarch to achieve that consistency.
My Jello slime breaks when I try to stretch it. How can I fix it?
First, try pulling more gently. Since this slime doesn’t have the same ooze as traditional slime you have to be more careful with it.
But if it still won’t stretch, try adding a bit more water (literally a few drops at a time) and knead it in.
This will allow the slime to stretch without breaking. Just play around with the cornstarch/water ratio until you get the texture you’d like!
How long does Jello slime last?
The Jello slime will only be stretchy when you first make it. If you set it in an airtight container it will become more like Jello playdough within a few hours. You can add a bit more water at a time to get it stretchy again, but it tends to dry out quickly. The dough will still be useable the next day, though you might need to knead in a few drops of water to make it softer.
Since this is a food item that can mold, we don’t recommend keeping the Jello playdough more than a day — unless you store it in the fridge. Even then, we see this as a “day of” type of slime, not one you keep longer term, like regular slime.
And that’s all it takes to make a batch of colourful, fruity Jello slime! With its thick, stretchy texture and taste-safe ingredients, this Jello playdough recipe is perfect for hours of squishy fun.
Whether you’re making it for a rainy day activity, a sensory play session, or just to try something creative and different, this edible slime is sure to be a hit!
