Step 1

Start by adding glue to a large mixing bowl

Step 2

Next, add a tiny bit of food coloring to your glue. Mix until the desired color is achieved. We used a very small amount to make a light blue color.

Step 3

Then, add in as much glitter as you’d like and mix well. We used about 1 teaspoon here.

Step 4

Add baking soda to the glue mixture and mix well.

Step 5

Finally, add in several squirts of saline solution and mix well. You want the mixture to not be sticky. So, keep adding solution and keep mixing until it does not stick to your hands.

Step 6

Knead well once it’s not sticky.
