Questions about slimes and slime care

How long do slimes last?

Depending on use and care, slimes can last for many weeks, many months, or even up to a year. However, it's normal for slimes to shrink over time due to the slime components, as air is removed, or liquid escapes.

To keep your slime in good condition for as long as possible, be sure to wash your hands before playing and only play with it on a clean surface to avoid dirt or bacteria getting into your slime. We also recommend not playing with the same slime for more than 15 minutes per day to prevent it from hardening quickly. After playing, store your slime in an airtight container in a cool environment. Reactivate your slime with slime activator as needed to prevent your slimes from melting. For more handling tips, see the Slime Care Sheets .

How do I fix my slime if it has hardened?

Slimes can become hard, especially in colder months, due to the nature of their ingredients. If the slime has hardened due to the outside temperature, let it stand for 1-3 days at room temperature or in a warm room. If the texture of the slime is still too hard after that, it helps to place the slime in its closed container on a heater. However, don't leave the slime on a hot heater for too long, or it will become too runny. Another tip for dealing with hard slime is to add a few drops of pure glycerin to the slime.
