Cook Up Some Edible Slime
Explore the properties of different ingredients and how they can transform while creating tasty (and safe!) edible slime.
What You'll Need
Directions
Combine the water and tapioca in a saucepan and stir until dissolved. Add five drops of food coloring (optional). Notice what happens.
Bring to a boil over medium-high heat while stirring constantly. You should notice the color change from opaque to transparent. Have children observe these changes from a safe distance.
Reduce heat and continue cooking for 5 to 10 minutes.
As the mixture starts to thicken, use the spoon to scrape along the bottom and the sides.
When the slime looks ready, pour into your heat-safe bowl and let it cool. Less cook time will produce a more liquid-y slime. Boiling the mixture longer will make it gooier. The mixture will continue to thicken overnight.
Explore Further
Use the slime to engage your child in a conversation about the chemistry and composition of the slime. What does the slime feel like? Is it a liquid like water? Or is it solid like a rock?
