Spooky Green Halloween Slime 

Get ready for some ooey-gooey fun! This spooky green slime is irresistibly squishy — perfect for little hands to stretch, squeeze and explore in the messiest, most playful way.

You’ll Need:

  • 180 ml glue or slime glue
  • 60 ml water
  • 1.5 tsp baking soda
  • 3 tbsp lens solution (must contain boric acid)
  • Green food coloring

Let’s Make it:

  1. Pour glue into a bowl—your little scientist can help with the squeeze.
  2. Mix in a few drops of green food coloring for that perfect “witch’s brew” slime. Stir in water to loosen things up.
  3. Sprinkle in the baking soda, then slowly add lens solution while stirring. Watch as the mixture begins to pull away from the bowl.
  4. Knead the slime until it’s smooth, stretchy and ready for hours of spooky fun.

Why We Love It:

  • Transforms a few simple ingredients into a magical, hands-on science experiment
  • Encourages curiosity and creativity through sensory play
  • Perfect for a Halloween party activity or a spooky afternoon at home

Did you know?

Glue is like a bunch of tiny strings (called polymers) that slip and slide around. When you add the lens solution, it makes those strings stick together. That’s why the glue changes from runny liquid into stretchy, squishy slime!
