(: 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


you can't hold it with your fingers.
