Remember, water can make or break your slime. Make sure you only add a little bit of water if you don’t want jiggly slime.
You can add more gel if it doesn’t soften on the first try.
Be sure you match the type of glue you add with the glue you made your slime with. For example, don’t add white glue to clear slime.
If it looks too runny at the end, add a dash of activator. Activator is just whatever you used to make the slime in the first place, such as half a teaspoon of Borax dissolved in a glass of water.
