This simple slime recipe for color changing slime is easy to make, and great sensory play. Color changing slime makes a great gift too!
Kids LOVE slime! It’s gooey, it oozes, and in this case, the slime changes color! It’s sure to inspire some scientific investigation when your kids want to know “How does it do that?!”
Playing with slime (and messy things in general!) is high quality sensory play. This simple slime recipe gets a bonus point for the additional visual element of color changing magic! Don’t fear the mess or the cost because it’s made from two washable ingredients.
Simple Slime Recipe for Color Changing Slime
The ingredient list for this simple slime recipe is blissfully short: color changing glue and liquid starch. It gets better- this slime is SO EASY to make. Once you’ve got your ingredients, grab a bowl and a measuring cup! We used a 1/2 cup measuring cup.
In your bowl, mix up equal parts of color changing glue and liquid starch. Knead the ingredients for a few minutes and the slime will form! If it seems too sticky, knead in a small amount of liquid starch until slime has reached your desired consistency. To make yellow to red slime, we mixed 1/2 cup of yellow to red color changing glue with 1/2 cup of liquid starch.
We used the same amounts to make blue to purple slime, but used blue to purple color changing glue! Both batches turned out beautifully.
When it’s time to put the slime away, it stores very well in an airtight container at room temperature for about 3 months. If it sits in the container for awhile, sometimes the slime will separate back into its original parts! Just knead it back together and it’ll be good as new!
Slime is Science!
Please do note that the slime has to be in UV light to change, and full sun is best. When the sun was setting, it didn’t change colors as well.
This creates a good opportunity to practice scientific observation with your young learner. Playing with it in the middle of the day and again in the evening will encourage kids to investigate what makes the slime change!
Consider asking questions such as:
- What does the slime do in the light?
- What happens when you put it in the shade?
- (In the evening) Does the slime change colors now? What’s different than earlier today?
This sensory rich simple slime recipe was a hit at our house! In full sunlight, my son kept running under the tree to let the slime change back to its original color before darting into the sun to watch it rapidly change again!
