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 !
