Tips for Making Slime

If you’ve never made slime before, here are some great tips you might be interested in. If you don’t need them, head on down to the recipe.

Measure Ingredients Precisely

The key to perfect slime is in the details. Measuring your ingredients as accurately as possible can make the difference between slime that’s just right and a recipe that’s too sticky or too brittle.

Add Mix Ins Slowly

If you’re adding color, glitter, or other fun elements, add them slowly and mix thoroughly to see the effect. You can always add more, but you can’t take it out once it’s in there.

Adjust Texture as Needed

If your slime is too sticky, add a little more activator (like borax solution, liquid starch, or saline solution). If it’s too stiff, add more glue or a bit of water. Do this gradually!

Use Supplies You Don’t Mind Getting Messy

Slime can get everywhere, and while it’s usually easy to clean up, it’s best to use tools (bowls and utensils) and surfaces you’re not worried about.

Use Your Hands

Once the slime begins to form, use your hands to knead it. This helps improve the texture and mix everything evenly. Don’t be afraid to get a little messy!

Storage is Key

Keep your slime in an airtight container when not in use. This will help it last longer and prevent it from drying out.

Safety First

Always use safe, non-toxic ingredients, and if you’re crafting with younger kids, make sure they’re supervised, especially with ingredients like borax.

Tips and Thoughts for This Craft

It’s really easy to recharge – you just need to take it out into the sun or under a bright light for several minutes!

Store your slime in an airtight container or baggie. If your slime gets stiff, you can try to add a little water – lotion – hand sanitizer – or even a bit more glue to soften and reactivate it.
