The Slime

In the next video, you will see :

- How to make a slime

- The components of a slime

- The result of the experiment

- The property of a slime

Equipment/Substances :

- A plastic Glasses - A spoon

- Borax - Ultraviolet light

-polyvinyl alcohol - Graduated Cylinder

-Glowing, coloring substances

( eosin, fluorescein, methylene blue )

- Soft drink with quinina

Protocol :

To make a slime you must :

- Mix the glowing and coloring substances with the borax in three tubes (in the first eosin + borax, in the second fluorescein + borax, in the last methylene blue + borax)

- Stir continuously with the spoon while you add the polyvinyl alcohol after a few minutes the substance becomes sticky

Observation :

- If you turn the glass over, the slime flows down but it's very slow

- When you put it under an ultraviolet light the slime shines

Conclusion :

- The slime seems to be a solid but actually it's a liquid because it takes the shape of its container.

- It's a secondary source of light because when you put it under an ultraviolet light, the slime diffuses the light
