CIY Staff Tips:

  • If slime is still too sticky after adding 3 tsp contact lens solution, add extra contact lens solution in small increments until the slime mixture easily slides out of the bowl. If needed, add a small amount of contact lens solution to your hands and rub them together before removing the slime from the bowl.
  • Adult supervision required. This project is not appropriate for children under the age of 3 years. Warning: If large quantities of contact lens solution are accidentally ingested (greater than a tablespoon), get medical attention immediately.
  • To keep slime from drying out, keep it in a resealable plastic bag or airtight container.


Step 1

Pour 3/4 cup glue, 1/8 tsp baking soda, and 1 Tbsp lotion into a bowl, stirring well with a craft stick until completely mixed.

Step 2

Dissolve 2–3 watercolour tablets in 1/4 cup warm water and stir until completely dissolved. Pour half of the coloured water into the glue mixture.

Step 3

Add contact lens solution in 1/2 tsp increments. Mix the contact lens solution in each time it’s added, up until 3 tsp have been added or until the slime mixture is easily coming off the bowl.

Step 4

Stir and knead until you have a smooth, well-mixed slime mixture.
