The objective of this activity is to demonstrate the use of polymers and one of their multiple properties from an informative point of view and with daily use materials.
The activity consists of preparing a cross-linked polymer (slime), based on daily use elements such as transparent glue, water and borax. In addition, food colouring is used to colour the polymer and a few drops of fluorescein (organic fluorophore) can be added to give it emissive properties after illumination with ultraviolet light.
Polyvinyl alcohol (PVA), a component of transparent glue, is soluble in water. However, when mixed with borax it forms a three-dimensional network that traps water creating a semi-solid gel known as “slime”.
