Slime making is one of those activities kids never seem to get tired of. It’s messy, stretchy, colorful, and surprisingly calming to play with. If you’ve ever tried making slime from scratch, you know it can be tricky to get the texture just right.
That’s why I decided to try the Elmer’s Slime Starter Kit, a popular all-in-one kit that promises easy, safe, and reliable results.
In this review, I made three different types of slime using the kit:
- Cosmic slime
- Metallic slime
- Clear slime
Here’s exactly what comes in the box, how it works, and whether it’s worth it for kids and families.
What’s Inside the Kit?
The kit includes:
- 1 bottle Cosmic Glue – 147 ml (5 oz)
- 1 bottle Metallic Glue – 147 ml (5 oz)
- 1 bottle Clear Glue – 147 ml (5 oz)
- 1 bottle Magical Liquid Activator – 258 ml (8.75 oz)
According to Elmer’s, the magical liquid is enough to make up to 8 batches of slime.
You’ll also need:
- Mixing bowl
- Spatula or spoon
- Measuring spoons
Prep Time
10–15 minutes per batch
Ingredients (Per Slime Batch)
- 1 bottle of Elmer’s glue (cosmic, metallic, or clear)
- 2 teaspoons magical liquid (activator)
- Extra magical liquid (as needed)
How to Make Slime (Step-by-Step)
The process is the same for all three glue types.
1. Pour the glue into a bowl
Empty one full bottle of glue into a mixing bowl.
2. Add magical liquid
Add 2 teaspoons of magical liquid to the glue.
3. Mix well
Stir slowly with a spatula or spoon. You’ll notice the mixture starting to thicken.
4. Adjust texture
If the slime is still sticky:
- Add a few drops of magical liquid at a time
- Mix again
- Repeat until the slime becomes stretchy and no longer sticks to your hands
Be careful not to add too much, or the slime may become rubbery.
5. Knead by hand
Once it comes together, knead it gently with your hands for about 1–2 minutes.
6. Repeat for all glue types
Follow the same steps for:
- Cosmic glue
- Metallic glue
- Clear glue
Each type has a slightly different look and texture, which makes the activity more exciting for kids.
7. Play & enjoy
Stretch it, twist it, poke it, or store it for later play.
