For backyard battles, surprise dad attacks, and pure pink chaos.
We used to publish a borax-based recipe here. We've switched to a kid-safe contact-lens-solution recipe because borax can irritate skin and eyes, especially when slime is flying around an outdoor battle. This new recipe is the standard one pediatricians and craft sites recommend for kids.
Always: adult supervision · do not eat · keep away from eyes, mouth, and pets · wash hands after play.
Makes 1 big throwable blob · 10 minutes · ages 6+ with adult help
💡 Pro tip: If your slime is too soft to throw, knead in an extra teaspoon of contact solution. If it's too stiff, knead in a splash of warm water with a pump of lotion.
Use black food coloring + purple + silver glitter. Looks like a tiny galaxy in your hand.
Mix in 2 cups of shaving cream before the contact solution. Light, airy, and even more throwable.
Swap the white glue for glow-in-the-dark glue. Bonus battles after dark!
Add 5 drops of food-grade scent oil. Strawberry & cotton candy are top tier.
Mix in pre-grown instant snow for an icy, crunchy texture that still throws clean.
Knead in foam beads or small water beads for crackly, satisfying squeezes.
This stuff washes out of most fabrics, but you don't want to test that on your favorite t-shirt.
Slime in eyes is no fun. Cheap swim goggles work great.
Grass, patio, driveway. Anywhere you can hose down after.
No throwing at faces or heads. Shoulders & below.
10-15 minute rounds. Then water break. Otherwise it gets feral.
Slime + curious dog = vet visit. Bring them inside before battle.
Two main causes: (1) your contact-lens solution doesn't contain boric acid/sodium borate — check the label, you need one that does, or (2) you added the solution too fast. Try adding 1 teaspoon at a time and stir between each.
Yes, when used as a craft and not eaten. The boric acid in contact solution is heavily diluted and bonded to the glue once mixed. Kids should still wash hands after playing, and keep slime away from mouths, eyes, and pets.
Yes — liquid laundry detergent (like Tide) works as an activator too. Use 1-2 tablespoons in place of contact solution. Same kid-safe rules apply (skin contact only, no eating).
Knead in a tiny bit more contact solution — like 1/4 teaspoon at a time. Going slow is the key. You can also rub a little lotion on your hands while kneading; it'll un-stick fast.
Yes! Add a teaspoon of warm water and a small pump of lotion. Knead for 2 minutes. Repeat if needed until you get your stretch back.
We've got pre-grown instant snow, scent oils, foam beads, and giant tubs of slime ready to ship.
Shop Supplies →With supervision, yes, for school-age kids. Keep it out of eyes and mouths, wash hands afterwards, and skip it entirely for children under three. If your recipe uses a borax or contact-lens-solution activator, an adult should mix that part; the concentrated solution can irritate skin and eyes before it is fully worked into the slime.
Yes. Cornstarch-and-water throw slime needs no activator at all, and a glue-based version can be set with liquid starch instead. Both are stretchier and messier than a borax-activated batch, which is usually what you want for throwing anyway.
Uncoloured slime does not stain. The dye does. Heavily pigmented food colouring and washable-paint slime will mark light fabrics, and concentrated colour can leave a temporary tint on patio stone and decking. Use half the dye you think you need, and keep the battle on grass rather than concrete.
Work in a little vinegar or conditioner, let it sit a minute, then comb or blot it out. Vinegar breaks the polymer bonds and the slime loosens instead of smearing. Do not start with water, which spreads it. For carpet, lift the bulk with a spoon first, then vinegar, then blot dry.
Kept in a sealed container it stays usable for one to two weeks. Once it has been thrown around outside it has picked up grass, dirt, and bacteria, so that batch is done. Mix fresh for the next battle rather than saving it.
