DIY Slime vs Slime Kits

After trying several kits, we prefer to make our own slime. Most slime kits we have tried have been too sticky to even play with. You can see for yourself with this Glow in the Dark Slime Kit video we recorded. The only slime kit success we have had is with this slime case. The slime in this slime case was the perfect consistency and easy to make. We also love how it comes with different glitters and charms to customize your slime. The only downside is it is almost too easy to make and you miss out on the fun of making it. But you do end up with a great case to store all your DIY slime accessories in and slime to play with!

What is Slime?

The advantage to making your own slime is you get a little science lesson as well. Slime is a polymer (similar to the instant snow and oobleck we have made) because it has qualities of both a solid and a liquid. When you add boric acid to the glue, it counteracts the glue and forms the substance of slime which can be shaped and stretched. It is a lot of fun to watch as the contact solution (boric acid) turns the glue into slime. If you love a good science project like we do, you can find more science ideas here.

Ingredients for Mermaid Slime

Making slime is usually very inexpensive and takes very few ingredients. For the most basic slime, all you’ll need is Elmer’s glue and either borax or contact solution. You can then add and customize depending on the type of slime you’d like to make. Today, I am here to show you how to make mermaid slime.

For this mermaid slime recipe you’ll need:

2 Bottles of Elmer’s Glitter Glue. We made 2 batches and mixed the green and blue together for one batch and the purple and pink together for another. You could also use clear glue and add food coloring and glitter to it. White glue will work also, you just won’t get the cool opaque feature like you do with the clear glue.

Glitter!! We used 1 small container of a larger sized glitter for each recipe. If you are using glitter glue, you could eliminate this to be more cost effective, but we love the look of all the glitter in this recipe.

2 TBSP of water. This step is optional. If you add the water, it will make your slime stretchier. It literally stretches for days!

1 – 2 TBSP of Contact Solution. It is very important that the brand you choose has boric acid and sodium borate.

1/2 TBSP of baking soda.

First you’ll mix your glues together in a bowl. We used all of the blue and half of the green. If you want more of a teal, you can use a little less green. Since the purple was such a small size, we used all of the pink and purple for the second batch.

Next, you’ll stir in the glitter, followed by the 1/2 TBSP of baking soda and 2 TBSP of water.

Then it’s time for the fun part! You’ll want to slowly stir in the contact solution, starting with 1 TBSP. If you add too much, the slime will be very hard to play with. Like we did with this DIY Cotton Candy Fluffy Slime that we made.

You’ll immediately start to see the mixture turn to slime. Once you see the mixture begin to turn to slime, but it is still very sticky, you’ll want to mix it with your hands. This will keep you from adding too much contact solution. As you play with it, it will get less sticky. You can then add a few drops of contact solution here and there until it no longer sticks to your hands. But make sure you kneed and play with the slime for a few minutes each time you add more contact solution before adding more.

  1. I had no idea that you could use contact solution for this! That’s both fascinating and a little disturbing to think I put it in my eye. But anyway… this is an awesome project for little ones. I don’t have any little ones but I might have to try it anyway…

  2. We enjoy doing our our projects and experiments here at home. What child does not enjoy slime? I pinned this to share with others. Happy playing!

  3. Fun! Love the glittery. My daughter is beginning to love play doh, and I’m thinking slime would be a lot less messy! I’ll have to give the mermaid slime a try!

  4. My daughter loves making slime, too. I haven’t tried it with glitter yet, and the Elmer’s glue is a great way to do that. I probably would’ve just dumped some glitter in it. I love the colors, too!

  5. Slime has taken over our entire house! My girls make it constantly. About half the videos on our YouTube channel are slime. My daughter’s room needs new carpet because of SLIME!

  6. This is such a great idea – my daughters would love to make their own. I love the idea of using the contact solution and would never have considered it before this.

  7. This is great, I may be willing to try this one. My girls love mermaids and want to make slime really bad.

  8. We instituted a slime ban in our house. But I’m thinking it’s time to break the ban so we can make this! Perfect activity for summer fun!

  9. I love glitter! It definitely gives slime-making a more interesting twist. My son has been able to make his own slime at a workshop before but it didn’t have glitter.

  10. Mermaid glue looks so fun! I have a 7 and 3-year-old, and we’ve been making different kinds of slimes lately, so we’ll definitely try this recipe! Thanks for sharing!
