Experiment 2 by Manon and Anaëlle

Materials:

We use plastic glasses, a spoon, ultraviolet light, gratuated cylinder, borax, polyvinyl alcohol, glowing, coloring substances (eosin, fluorescein and methylene blue), soft drink with quinina and U$!!

Experiment:

Mix borax, polyvinyl alcohol, and glowing subtances each three plastic glasses.A jelly immediately sticks to the spoon. Keep stirring and squeeze the substance against the side of the glass until the substance is homogeneous.In front of the camera, pick up all the slimes between your fingers and manipulate them with classical white light and then do the same with ultraviolet light only

Observation:

First it sticks to your fingers. Then it slowly flows down on the table just as jelly. It takes the shape of the glass.

Conclusion:

The slime is liquid.

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