❓ Alphabet Slime FAQ

Is borax slime safe for kids?

  • Borax slime can be safe when used with supervision and proper hand washing after play. If you prefer a gentler option, you can try a borax-free slime recipe instead.

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.
