For this experience, we needed :

-Equiment as plastic glasses, spoon, ultraviolet light and gratuated cylinder.

-Subtances as borax, polyvinyl alcohol, glowing coloring subtances (eosin, fluorescein, methylene blue and soft drink with quinina.

 

Protocol :

We add four drops of colorant in three glasses (eosin in the first glass, fluorescein in the second glass and metylene blue in the third). Then, we mix it to make a substance homogenous.

 

Observations:

We can take the slime in our hands during few minutes. With ultraviolet light, it porduces a glowing light. It takes the shape of the container but only during few minutes and it's slow.

 

 

Conclusion :

The slime is liquid because it takes the shape of the container but it slow

it's a secondary light source.
