Ingredients

• Elmer’s glue (most kinds of white craft glue will work)
• 2 disposable cups
• Food coloring (you pick the color)
• Water
• Borax Powder (available at most large grocery stores near the laundry detergent)
• A plastic spoon (for stirring)
• A tablespoon (for measuring)

 Directions

• Fill one small cup with water and add a spoonful of the Borax powder and stir it up. Then set it aside.
• Fill the other small cup with about 1 inch (2.5 cm) of the glue.
• Add three tablespoons (20 ml) of water to the glue and stir.
• Add a few drops of the food coloring and stir it up until mixed.
• Now the fun part…Add one tablespoons of the Borax solution you made earlier and stir well. Watch the slime form!
• After the slime forms let it sit for about 30 seconds and then pull it off the spoon and play with it!

Science

• Solid molecules are tight together, liquid molecules spread out and break apart (drops)
• POLYMER molecules CHAIN themselves together (they can stretch and bend like chains) and that makes them special. Jell-O, rubber bands, plastic soda bottles, sneaker soles, even gum are all forms of polymers.
• The polymer you made should be kept in a sealed plastic bag when you aren’t playing with it. Also, be sure to keep it away from young kids or pets who might think it’s food. Have fun!
