Materials:

• 8-ounce bottle Elmer’s white school glue

• 1 1/2 – 2 Tablespoons contact saline solution, more as needed

• 1 Tablespoon baking soda

• Food coloring, optional
  

Directions

1. Add glue and food coloring to bowl. Squeeze the bottle of glue into a bowl. Add your food coloring if desired, and stir until combined. Then mix in baking soda.

2. Mix in saline solution. Add 1 1/2 Tablespoons saline solution and mix until combined . If it’s too sticky, add 1/2 Tablespoon more solution at a time. The more you add, the thicker it’ll be. The less you add, the slimier it’ll be .

3. Knead the slime. Using your hands, knead the slime until it holds together. It will be wet and gooey at first, but just keep kneading until it all comes together.

4. Store slime. Store slime in a container with lid, or in a zip top bag. The slime is best to play with on a place mat.

Science Behind This:

In order to make slime certain ingredients are necessary such as slime activators. These would include borax, contact solution, and saline solution. Cross linking occurs when the glue and the activator are combined resulting in the slime. Slime is also a non-Newtonian fluid since it is neither liquid or solid. It has properties of both states of matters. Slime doesn't have a shape but it can be picked up as a solid and ooze like a liquid.
