Need a quick and easy last minute gift for kids and teens? Any slime making enthusiast will love this Homemade Slime Making Kit! Make a slime kit for birthday gifts, Christmas gifts, or “just because” days.

Kids of all ages will love a kit to make their own slime and parents love that it is borax free.

How to Make a Homemade Slime Kit

It’s official. My kids are 125% totally and completely addicted to making homemade slime. All their friends are, too. This scene in my kitchen is almost a daily reality and a good portion of the time it drives me completely and totally up the way…just being totally honest here.

My kids are older now than when I first published this post, but they still love slime. Slime kits in the stores are expensive. You can make your own for a lot less money – and then it’s more customizable, too.

Put together a gift kids will really appreciate this year. My kids helped me make this ultimate list of things you need to make slime. You’ll have everything you need to make your own DIY Slime Making Kit.

What to Include in Homemade Slime Making Kit

There are two essential ingredients to borax-free slime that you must include in any slime making kit:

• White Glue: This is the bulk of the slime.
• Activator: Most slime recipes call for borax as the activator but it can be dangerous if used improperly. My daughters’ favorite activator is liquid starch– Elmer’s Magical Liquid works so well! You can also use baking soda and contact lens solution, but Anna thinks it’s hard to work with plus, contact solution is expensive. The nice thing about liquid starch is that it’s also cheap (<$3 at Walmart).
• Customizable Items: Add beads, glitter, small confetti or small toys to your slime kit for that special, customized flair.
• Storage containers with lids: Keep slime contained in an airtight container so it lasts a long time. My kids have used these plastic food storage containers but glass jars with lids also work well.
• Essential Oils: I would only include these in slime kits for older kids and make sure parents are aware they are included and how to use them properly.
• Slime Recipes: Include a slime recipe book or recipes written on index cards for inspiration. If you have any slime hacks, include them in the gift box as well.

My kids learned several slime making tips from the book Ultimate Slime Extreme Edition by Alyssa Jagan. They definitely honed their slime recipes. Anna learned how to make more interesting slime with all the add-ins and what to do if she added too much borax. She also found other recipes to make slime without borax.

How to Assemble a Slime Kit

Once you have all the ingredients, add-ins, slime recipes without borax, place them in our favorite rope basket with tissue paper or even in a shoe box. Kids love to decorate old boxes and make them look fancy. Put a bow on it and – Voila! you have a homemade slime kit gift box that is way more affordable than a store bought one.

How Long Does Homemade Slime Last?

If stored properly, homemade slime should last 1 to 2 weeks. Keep it out of direct sunlight and heat. If there are any signs it has gone bad, discard it. Mold and a bad smell are two indicators the slime has gone bad.

What to Do If DIY Slime Dries Out?

Try adding a very small amount of water or lotion to the slime. Sometimes this will restore the texture, but not always.

What are the Best Add-Ins for DIY Slime Kits?

The best part about making your own safe slime kit is customizing it for each person. Do they have a favorite color or symbol? Here are several add-in ideas for customizing your slime kit gifts.
