Hands-On Wednesday: Fluffy Slime


Do you love to play with gooey slime? You can create your very own slime with just a few simple ingredients. When you add all of the ingredients, they work together to create a slimy polymer. Polymers are collections of continuously repeating molecules. The glue is a liquid polymer by itself, but when you add the contact solution, it cross links the long strands of glue molecules so when you pull out one chain of slime, all the rest comes with it in a blob!


  • Shaving Cream
  • Bottle of Elmer’s Glue
  • Food Coloring
  • Baking Soda
  • Contact Solution
  • Large Bowl

How to:

1) Add the following ingredients to a bowl in the order they are listed:

  • 3.5 bottles of shaving cream
  • 5 4oz bottles of Elmer’s glue
  • 30 drops of food coloring of choice
  • 5 tsp baking soda
  • 10 tbsp contact solution

2) Stir vigorously for 5-10 minutes.
3) Get messy!

This slime has another cool property. It has a lot of viscosity! Viscosity is a fluid’s resistance to flow. Water likes to flow very fast. Think about when you pour out a glass of water — it quickly spills to the ground. This means water has a low amount of viscosity. Not all liquids are in such a hurry to get somewhere! Have you ever put maple syrup on your pancakes? Does maple syrup come out as fast as water? No. So, we say that maple syrup is more viscous than water. Polymers, like this slime, tend to be more viscous. That’s why this slime moves more slowly between your hands as you play with it!
