Why is my slime too sticky?
- If your slime is sticky, it just needs a little more activator. Add a very small amount at a time and knead well until it becomes smooth and stretchy.
Why is my slime too stiff or rubbery?
- This usually means too much activator was added. Try kneading in a small amount of warm water or lotion to soften the slime.
