6. 1.In a container, mix together one tablespoon of glue, one tablespoon of water and one drop of green food coloring. 2. In a different container, dissolve one teaspoon of borax powder in one tablespoon of water. Borax powder is poisonous so wash your hands after touching the slime or borax powder. 3. Pour the borax mixture into the Glue mixture and mix with your fingers-a slime should form instantly! 4. Store in an airtight container
7. The glue and borax mix together to make a new chemical-slime! The borax stops the glue flowing like a liquid. The slime is very elastic so it can stretch and bounce!
