-3 tsp Thermochromatic Pigment

-1 tbsp water

-food coloring (color slime changes to)

-¼ cup white glue

-¼ cup liquid starch



Step 1: Mix the glue and water together in a bowl with a spoon. Then, add food coloring and mix. The color food coloring you use will result in the color the slime “changes” to when it reacts to a temperature change. 

Step 2: Mix in the thermochromic pigment. Add half of the starch. Mix. Add the remainder of the starch and mix.

Step 3: Remove the slime from the bowl. Knead the mixture, and examine its texture. If the slime is too sticky, add more starch in small amounts. If not, then start playing with your new creation. The slime reacts to heat and coolness. If you lay it across a cool surface, then the slime will change to the color food coloring you originally added. 

The slime can be stored in an air-tight container in the fridge for up to one week.
