1. Polyvinyl Alcohol (PVA) Glue: This is the most common alternative to borax. PVA glue itself is a polymer, and when mixed with an activator like liquid starch or borax, it forms long chains that create the slime.
2. Liquid Starch: While not as strong as borax, liquid starch can act as a cross-linker for PVA glue, creating a slime with a smoother texture.
3. Contact Lens Solution: Some contact lens solutions contain boric acid, a chemical similar to borax, which can be used to activate PVA glue and make slime. However, it's important to note that not all contact lens solutions contain boric acid, and using the wrong solution can be dangerous.
4. Sodium Tetraborate: This is a chemical very similar to borax, and it can be used to make slime as well. It's available in some stores, but it may be more difficult to find than borax.
5. Borax Substitute: There are several commercially available borax substitutes, often marketed as "slime activator" or "slime magic." These are typically based on a combination of chemicals that act as cross-linkers.
Safety Note: Always supervise children when making slime, and ensure they understand the importance of washing their hands thoroughly after playing with it. Some substances, like borax, can be harmful if ingested.
