Slime Time

Warning!

Adult supervision: liquids not for drinking

Please read the procedure before beginning! After reading, please watch the video. Some activities require more time and cleanup than others. You also have the choice of performing these activities in a way that suits your needs.

Not for children under 3 years. Adult supervision required. Follow approved procedures.

Materials

· Measuring Cup

· White Glue

· Shaving Cream

· Vial of Food Coloring

· Tongue Depressor

· Tablespoon

· Liquid Starch

· Saline Solution

Procedure

1. Find a workspace that can be easily cleaned.

2. Find the fluid ounce (oz) measurements on the side of the measuring cup. Pour 1 fluid ounce of white glue into the cup.

3. Add shaving cream to the cup until it is almost full.

4. Pour in the vial of food coloring.

5. Stir the glue, shaving cream, and food coloring with the tongue depressor. Scrape the bottom of the cup to ensure that all of the glue is being mixed in. The mixture will be slightly sticky when it is evenly mixed.

6. Add 1 tablespoon of liquid starch using the provided tablespoon. Stir quickly! The slime will become stretchy.

7. To reduce the stickiness and complete the slime, add a small amount of saline solution and combine everything with your hands. Keep adding drops of saline solution until the slime no longer sticks to your hands.

8. Your slime is completed! Place the slime in the bag labeled ‘Slime Time’ to keep it from drying out!

Science Behind it!

In this science experiment, we are making fluffy slime that will resemble the shape of a cloud in the sky. This is all about chemistry, which is the study of the states of matter that include solids, liquids, and gases. Everything in the world is made of matter, atoms, and molecules. These are the tiniest specks of particles that make everything. Chemistry is what happens when different materials are mixed together and how they react when they are mixed together.

Slime is neither a solid or a liquid. It is called a non-Newtonian fluid. This fluid can have properties and act like a liquid or solid. It can be picked up like a solid such as an apple, but it will also ooze like a liquid such as water. Try putting your slime in a container and then try to flip it over to build a “sand castle” on the table you are working on. What happens? Can this slime bounce? Pull it, squeeze it, twist it, bop it with your hand. What other neat properties does this slime have?

When you create slime and put together the glue and activator (saline), you are making chemical bonds which is called cross-linking. You are physically breaking the chemical bonds between glue and saline when you stretch it quickly.

Enjoy the slime and see what other types of cool science slime you can make!
