* Polyvinyl alcohol (PVA): This is a synthetic polymer that forms long chains and provides the slime's stretchy texture.
* Borax (sodium borate): This acts as a cross-linking agent, connecting the PVA chains together to form a gel-like structure.
* Water: This acts as a solvent and helps to dissolve the borax and PVA, allowing them to interact.
Other ingredients might be added, like glue, cornstarch, or food coloring, but PVA and borax are the key components that give slime its unique properties.
