The kids are going to love this Space Slime Recipe! It’s a fun way to get a little bit messy while dreaming of space!

Kids love slime and things that glitter. Right now, sparkly galaxy slime is popular as it should be. It’s beautiful. It is mesmerizing. Even I, as an adult, want to get my hands on it. Unfortunately, slime, and especially specialty slime-like galaxy slime, are costly. Even worse than the cost is that slimes tend to dry out incredibly fast.

Within days of opening, your new slime purchase has turned into a sparkly, galaxy rock. Unless that is what you are going for, there is good news. Did you know you can make space slime for much less? You can gather the simple ingredients and whip up a quick batch of galaxy slime in a flash.

Possibly with ingredients that you already have in your home right now. Sometimes I will involve my kids in the space slime-making process while other times I am not interested in the mess so I make the slime on my own and give it to my kids to play with after. They are happy kids to have Space Slime of their own.

All you need are the following ingredients to make slime. Who knew that slime was such a simple process? So many people say no to making slime and I really think it’s because they think that it’s a tedious process.

4 oz school glue
4 oz water

black watercolor paint or food dye

Slime Directions

I highly recommend that you make this slime recipe together as a family. The more that everyone can join in on the fun, the more fun the process is going to be.

Each person can easily take a step and be a part of the slime making process.

In a large bowl mix school glue and water until blended smooth.

Add large drops of coloring blending as you go, until the shade you desire is reached. The darker the better.

Add glitter mixing until blended. This will help ensure it spreads in more rather than waiting until the slime is activated.

Once you’re happy with the color and amount of glitter of your slime, it is time to add your liquid starch.

Add in the starch and mix well until the liquid transforms into thick stretchy slime. Now you’re ready to let the kids play. The first few minutes of the kids playing will also be ensuring that the slime is mixed well.

You can easily have them stretch the slime and pull the slime and talk about what the slime looks like. Slime is a great way to deal with stress and anxiety or to show them how simple it can be to create something awesome from items that they have at home.

The slime will then be stretchy, squishy and so much fun. Make certain that you challenge them to pull the slime as far apart as they can without tearing it. They’ll love the challenge and you’ll love seeing them try to beat their best attempt!

As you can see the glitter, because we used big flecks, does not get all over the kids hands. The slime also does not stick to hands either.

There might be a time during the initial process that it’s sticky but the more that it’s worked and played with, it really isn’t that big of a concern.
