Pour 1 cup of Maddie Rae's White Slime Glue into a bowl. Add 1 cup of water and stir.
The color of the Thermochromic Pigment you choose will be the color of your slime when it's cool. The food coloring you choose will be the color when it's warm. For my project, I chose a red thermochromic pigment, and yellow food coloring. Add your thermochromic pigment and food coloring to the glue solution and stir until dissolved.
Add 1 to 2 pinches of baking soda. Mix slowly until dissolved.
Add 2 squirts of saline solution
Mix continuously until slime starts to form. Continue to add additional saline solution until you reach your desired consistency.
Store your slime in an air tight container for up to a month.
If it's been a few days since you've played with your slime, add a few additional drops of starch into the slime and knead it to help it out!
The more you knead and play with your slime, the firmer and less sticky it will become!
