The Slime

 

Materials

 

  • Equipement

We use : -Plastic Glasses

               -A spoon

               -Ultraviolet Light

               -Graduated cylinder

 

  • Substances

We use : -Borax (also know as soduim tetraborate)

               -Polyvinyl alcohol

               -Glowing, coloring substances (eosin, fluorescein, methylene blue)

               -Soft drink with quinina

 

Experiment

 

We have put 10 mL in each of three glasses.

After thah, we add eosin in the 1st glass, fluorescein in the 2nd glass, methylene blue in the 3rd glass.

We mix it and we finaly add the slime with different colors.

 

How does it work

 

The contact of borax and polyvinyl alcohol produces a sticky and slimy substance. It glows in front of ultraviolet light.

 

Conclusion

 

The slimes diffuses (spreads in all directions) another source's light as a consequence it's a secondary light source.

The slime is liquid.
