Materials

- Measuring cup

Full Step-by-Step
Step 1: Prepare the Crayons
- Peel and Break: Remove the paper from the crayons and break them into smaller pieces, about 1-inch long. This helps them melt evenly.
Step 2: Melt the Crayons
- Heat: In a microwave-safe bowl, combine the broken crayon pieces and 1/2 cup of water. Microwave in 30-second intervals, stirring in between, until the crayons are completely melted and mixed in.
Step 3: Combine Ingredients
- Mix Glue and Baking Soda: In another bowl, mix 1 cup of white school glue and 1 teaspoon of baking soda. Stir until combined.
- Add Crayon Mixture: Slowly pour the melted crayon mixture into the glue and baking soda mixture. Stir thoroughly to combine the colors.
Step 4: Activate the Slime
- Contact Solution: Gradually add 1 tablespoon of contact lens solution to the mixture. As you add the solution, the mixture will begin to clump and form slime. Keep stirring until it starts to pull away from the sides of the bowl.
Step 5: Knead the Slime
- Hands-On Fun: Once the slime has formed, use your hands to knead it for a few moments. This will help improve the texture. If it feels too sticky, add a few drops of contact solution and knead again.
Tips & Variations
- Add Glitter: For extra sparkle, mix in some glitter or small beads during the combining step.
- Different Textures: Experiment with different ratios of glue and baking soda to achieve your preferred slime consistency.
- Scented Variety: Consider adding a few drops of essential oil for a pleasant scent.
