Help!?

If I don't have saline contact lens solution or air-dry clay, what can I use instead?

Use liquid starch (add 1 tablespoon in the same step where you would add saline) or a borax solution made by dissolving 1/2 teaspoon borax in 1 cup warm water and adding a little at a time to activate the slime, and substitute modeling clay, oven-bake clay, or a small rolled-up piece of aluminum foil decorated with glitter for the DIY star.

My slime is too sticky or won't form — which step is likely the problem and how do I fix it?

If the mixture doesn't pull away from the sides after you 'add 1 tablespoon of saline contact lens solution' and then knead for about 2 minutes, add one or two extra drops of saline while kneading until it firms up, and if it becomes too stiff or crumbly, add a few drops of warm water and continue kneading until it becomes stretchy.

How can I adapt the activity for younger children or make it more challenging for older kids?

For preschoolers, have an adult pre-measure the 1/2 cup white glue, 1/2 cup warm water, and 1/4 teaspoon baking soda and supervise stirring and pressing the clay star, while older kids can experiment with different food coloring amounts, types of glitter, mix-ins during the 'add food coloring and glitter' step, or scale up to multiple batches and stars.

What are easy ways to extend or personalize the slime and glittery star after the activity?

Press a small hole in the air-dry clay star before it fully dries and attach a jump ring to clip it onto the slime as a charm, or personalize the slime by mixing in foam beads, sequins, or glow-in-the-dark pigment during the 'add food coloring and glitter' step.

Facts about sensory crafts for kids

🧪 Slime became a huge DIY trend on social media because people love sharing satisfying, squishy textures and colorful mixes.

🪄 Borax is a naturally occurring mineral often used as a slime activator — but it should be handled carefully and used in small amounts.

✨ Glitter gives slime its sparkle, but most craft glitter is plastic; biodegradable glitter is a greener choice for charms and decorations.

🔬 White school glue contains polyvinyl acetate, and when it meets a borate activator it forms stretchy slime through polymer cross-linking.

🌟 DIY star charms can be made with clear resin, air-dry clay, or laminated glitter paper to add a sparkly keepsake to your slime kit.

How do I make colorful, stretchy slime and a glittery DIY star charm in the Slime Making Challenge?

Set up a protected work surface and gather supplies. For slime: pour 1/2 cup PVA school glue into a bowl, add a few drops of food coloring and glitter, stir. Add 1/4 teaspoon baking soda, then add saline solution drops while stirring until the mixture pulls away from the bowl. Knead until smooth. For the star charm: shape air‑dry clay into a small star, press in glitter, let dry, seal with clear craft sealer and attach a loop or thread. Combine by tucking the dry star into the slime or use it as

What materials do I need for the Slime Making Challenge W/ DIY Star @Craftbunny?

You'll need: PVA school glue (clear or white), saline contact lens solution, baking soda, food coloring, fine glitter for slime and charm, small mixing bowls, measuring spoons, spatulas or craft sticks, air‑dry clay or shrink‑plastic sheets for stars, clear craft sealer or Mod Podge, string or jump rings, scissors, disposable work mats, and wet wipes for cleanup. Choose non‑toxic, child‑safe brands and avoid borax powders for young children unless supervised by an adult.

What ages is the Slime Making Challenge suitable for?

This activity suits children ages 6 to 12 with adult supervision because it uses small parts, measuring, and activators. Older kids (10+) can be more independent, while younger children (4–5) can help with stirring, adding glitter, or molding the star with close adult help. For toddlers, use pre‑made slime and large‑safe parts only. Tailor tasks to each child's motor skills and attention span.

What safety tips should I follow during the Slime Making Challenge?

Safety first: use non‑toxic PVA glue and child‑safe glitter. Avoid powdered borax for young kids — use saline plus baking soda or liquid starch as activators with supervision. Keep slime away from eyes and mouth, and wash hands after play. Supervise when using air‑dry clay, sealers, or heat (shrink plastic). Work on a washable mat, wear aprons, store slime in sealed containers, and don’t flush slime down drains. Stop if skin irritation occurs and consult a doctor if ingestion happens.
