DIY Styrofoam Slime Cool Science Experiment
In this fun and easy cool science experiment for kids, we’re going to show you how to make do-it-yourself Styrofoam slime.
- Styrofoam cups or Poly-Fil Micro Beads
- Hot water
- Warm water
- Food coloring
- Borax powder
- White Elmer’s Glue
- Measuring cups
- Measuring spoons
- Mixing bowls
- Gallon size Ziplock freezer bag
- Break up four or five Styrofoam cups and put them in your blender. Add about a tablespoon of water and use the pulse button on your blender to break up the pieces into small bits.
- Put ½ cup of hot water in a mixing bowl and then mix in 2 tablespoons of Borax powder. Keep mixing until the Borax dissolves.
- In a separate mixing bowl, mix together a ¼ cup of warm water with a ¼ cup of white Elmer’s glue. Go ahead and feel free to add some food coloring if you prefer at this point and mix it in thoroughly.
- Now pour the glue mixture and the borax mixture into the ziplock bag.
- Then, add about 1 ½ cups of the ground up Styrofoam cups into the ziplock bag. You can add more or less Styrofoam later to get the consistency you desire.
- Zip the bag closed and squish the contents around to mix the ingredients together. Keep squishing until the contents begin to solidify.
- Remove your batch of Styrofoam Floam from the ziplock bag and enjoy.
How it Works:
Slime is is created when a chemical reaction occurs between the borax and glue. This chemical reaction combines the two ingredients permanently. Adding Styrofoam is fun and also allows you to investigate the properties of slime as the Styrofoam never permanently combines with the slime.
Make This A Science Project:
Try different activators like saline solution or liquid starch. Try adding pompoms. Try adding beads. Try adding cotton balls.
