DIY NON-Toxic Slime

Technically edible; but it wouldn’t taste that great… However, since this slim *IS* edible, that means it is perishable.  It will need to be stored in the refrigerator in a sealed container when not in use.  It can keep for up to a week, but please inspect it for signs of mold or foul odor before presenting it to your child for play each time.

1/4 cup chia seeds

2 cups of water

1 teaspoon of xanthan gum

3-5 drops food coloring (optional)

one full 16 oz box of cornstarch (+5 additional Tablespoons of cornstarch)



  1. Place chia seeds and 2 cups of water into a seal-able container and store overnight in the fridge (12-24 hours). Stir at least once because the seeds tend to clump.
  2. Remove from fridge. Stir to break up any clumps, then add 1 teaspoon of xanthan gum and whisk. (It won’t completely mix in, but that’s OK.)
  3. Add 3-5 drops and mix well.
  4. Add one full 16 oz box of cornstarch a cup at a time, and mix. At some point, it gets easier to knead by hand.
  5. After that continue adding cornstarch by the Tablespoon until the slime isn’t sticky.
  6. Your slime is ready when you can move it as a big heap. (If it’s crumbly and not stretchy, add a teaspoon of water to correct and knead well.)
