(: The Slime :)

(science experiment 2)

 

 

Materials :

 

We use plastic glasses, a spoon, an ultraviolet light and a graduated cylinder.

We use a lot of substances, like borax, polyvinyl alcohol, glowing coloring substances ( eosin, fluorescein, methylene blue ) and a soft drink with quinina .

 

Experiment :

 

We mix borax, polyvinyl alcohol and glowing substances         ( eosin, fluoroscein, methylene blue and quinina ).

 

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 slime is a secondary source of light; it diffuses the ultraviolet light, it doesn't produce any.

The Slime isn't solid ; it has characteristics of a liquid :

Its surface is always flat and horizontal,

it takes the shape of its container

and

you can't hold it with your fingers.
