DIY Slime Kit Gift: What to Put Inside
How to put together a homemade slime kit as a gift: what goes inside, the recipe card, the activator handed to an adult, wrapping ideas and a boron-free version.
A kit for making your own slime is a gift 7- to 12-year-olds really love, whether for a birthday, the holidays or the end of the school year. Putting it together yourself often costs less than a store-bought kit, lets you choose ingredients you know, and makes it easy to put safety first. Here’s what to put inside, how to wrap it, and an activator-free version for younger kids.
The idea: a kit, not ready-made slime
The kid makes their own slime, with an adult. So the kit brings together the dry and decorative ingredients, a clear recipe card and the tools. The only ingredient that needs special attention, the activator, is handed to the adult, not tucked into the box among the glitter.
What goes in an “easy slime” kit
| Item | Suggested amount | Why |
|---|---|---|
| Washable PVA school glue (white or clear) | 2 bottles of about 4 fl oz (120 ml) | Enough for two slimes (see which glue to choose) |
| Baking soda | A small labeled bag or jar | ½ teaspoon per slime |
| Food coloring or washable paint | 2 or 3 colors | Picking your color is half the fun |
| Glitter, confetti | 2 small jars | For glitter slime |
| Fishbowl beads | 1 small jar (if the kid is over 3 and has no baby brother or sister around) | For crunchy slime |
| Empty jars with lids | 2 | To store their creations |
| Bowl, spoon, measuring cup | 1 of each | Everything’s ready to go |
| Printed recipe card | 1 | The steps and the safety rules |
Give this to the adult separately: contact lens solution whose label lists boric acid and sodium borate. Why separately? Because ANSES, France’s food and health safety agency, advises against children handling these products repeatedly. It’s all explained on our slime activator page.
The recipe card to tuck into the kit
Just copy the steps from our easy slime recipe: ½ cup (120 ml) of glue and ½ cup (120 ml) of warm water, the color, ½ teaspoon of baking soda, then the contact lens solution added little by little by the adult, and two to three minutes of kneading. On the back, add the golden rules: wash your hands before and after, no tasting, close the jar, plus the address of our Slime Fixer in case something goes wrong.
Wrapping it up
- A shoebox covered in wrapping paper, or a glass jar for smaller kits.
- Labels on every jar (“baking soda,” “gold glitter”…): nothing should look like candy.
- A ribbon and a coupon that says “Good for one slime session with…”: the adult giving the gift offers their help too.
The activator-free version for younger kids
For a child under 6, or if you’d rather avoid any product containing boron, give a homemade playdough kit: in a jar, the dry ingredients for no-cook playdough (2 cups (480 ml) of flour, ½ cup (120 ml) of salt, 2 tablespoons of cream of tartar), with a label listing what’s left to add (2 tablespoons of oil, 1 cup (240 ml) of hot water poured by the adult, food coloring). Add some cookie cutters and a small rolling pin. Another idea: a cloud dough kit, with the flour in a jar and a label that reads “+ 1 part oil for every 5 parts flour.”
How much does it cost?
Prices vary by store and brand: compare glue bottles (bigger bottles cost less per ounce) and reuse empty jars from around the house. A homemade kit also lets you skip slimes and kits sold on faraway online marketplaces, which European consumer tests regularly flag for boron levels that are too high (see our parents’ guide).
A little extra kids love
Add a “Challenge” card with the address of the Daily Slime Challenge and the Slimer’s Logbook: the kid can take on a new challenge every day and collect badges, with no account and no sign-up.
