How to Set Up the Fluffy Slime Science Experiment

There is nothing you have to do in advance for this project, it’s super fun and requires no prep in advance other than making sure you have laundry starch (which can be difficult to find in stores).

You’ll need just a few things for this project:

  • Sta-flow liquid laundry starch
  • White school glue
  • Food coloring
  • White shaving cream
  • Measuring cup
  • Bowl

Add 4 ounces of glue and one cup of shaving cream to a bowl. Add food coloring and stir.

Add 1/2 a cup of liquid laundry starch to the mixture. Add the starch slowly, as you might not need all the starch to form the slime. Keep adding starch until the slime is fluffy and no longer sticky.

Fluffy Slime Science Explained

Fluffy slime is just like regular slime except that the addition of shaving cream gives it a slightly different texture than usual. Slime is made by a chemical bonding process between molecules in the glue and molecules in the starch. The broax molecules in the starch combine with the glue molecules, making long polymer chains similar to what is found in flexible plastic. This is why slime stretches and bounces instead of breaking.
