 The slime

 

 

Here are the substances and the material we need:

  • Borax (sodium tetraborate)
  • Polyvinyl alcohol
  • Glowing, coloring (eosin, fluorescein, methylene blue)
  • Soda with quinina

 

  • Plastic glasses
  • A spoon
  • Ultraviolet light
  • Graduated cylinder

 

Protocol:

We mix borax, polyvinyl, coloring substances and soda with quinina in a plastic glass.

 

 

What do we happens ?

We happens a sticky jelly which flows on the table. It takes slowly the shape of its container; but we can take it with our fingers. The slime is a secondary source of light because it diffuses the ultraviolet rays in all directions.

As it takes the shape of its container, it's liquid !
