Kids’ Christmas Slime Science Activity

slime recipe

Celebrate Christmas—with slime? That’s right! Your child can create her own batch of holiday-themed slime, with your help of course. This science-centered activity helps your child to make discovery and explore states of matter. Along with the science focus, it’s also a fun-filled way to celebrate at holiday time. As your child makes and plays with the slime, ask her a few open-ended questions. This might include, “What do you think will happen to the ingredients when we mix them?” or, “How do you think the ingredients changed as you put them together?”


  • Water
  • Clear Elmer’s glue (look for clear glue, not “clear-drying” white glue)
  • Liquid starch
  • Red and green glitter or sequins


  1. Mix equal parts water and glue. For example, if you’re using ½ a cup, mix ½ cup of water with ½ cup of glue.
  2. Add the liquid starch to the glue and water. Mix in an equal amount (for the above example, you would use ½ cup). Keep mixing the ingredients until they feel like slime. It should be stretchy, but not too liquidy or runny.
  3. Stir the red and green glitter or sequins Your child can add as much (or as little) as she wants.

Keep in mind, this is not a taste-safe mix. Your child should never put the slime (or any of the ingredients) near or into her mouth. Always supervise your child closely at all times when preparing and doing this Christmas slime activity.
