How to use

The best practice for playing with slime is to keep it on a non-porous surface, such as a plastic tray or plate, to prevent it from sticking to surfaces and making a mess. It is also important to wash your hands before and after playing with the slime to keep it clean and free of debris. Additionally, it is recommended to not put slime in your mouth or ingest it, as it is not intended for consumption and can be harmful if ingested. When you're done playing, store it in a airtight container to prevent drying out.

Q: "My slime is melted or stiff..."

A: Melted slime can be fixed by adding a small amount of activator solution, such as borax or contact lens solution, to the slime and stirring it well. The activator solution will help the slime to harden and regain its original texture.

If your slime has become hard, you can try adding a small amount of lotion or hand sanitizer to it and kneading it until it becomes soft again. You can also try heating the slime gently in the microwave for a few seconds, then stirring it well to help it become soft again.

If your slime has become ruined, it may not be possible to fix it. In this case, you can try starting over with a new batch of slime using the proper ingredients and following the instructions carefully.

To prevent slime from melting or becoming hard, be sure to store it in an airtight container and avoid exposing it to extreme temperatures. It's also important to follow the recipe and use the correct amounts of ingredients to ensure that the slime turns out correctly.
