Pros

  • โ€ขComes in an organized hard plastic 'briefcase' that keeps everything tidy and prevents spills.
  • โ€ขClear instructions with fun, varied slime recipes and encourages a love for science.
  • โ€ขEngages children creatively, reducing screen time and sparking imagination with colors and sparkles.
  • โ€ขCreates a good amount of slime for prolonged fun and has prade slime available for instant play.
  • โ€ขHighly recommended for family fun, encouraging activities together beyond the screen.
  • โ€ขProvides a creative outlet with options like glitter, foam beads, and water beads for stress balls.

Cons

  • โ€ขSome instructions are unclear and experienced users struggle to make slime successfully.
  • โ€ขInsufficient ingredients for the promised amount of slime; additional purchases are recommended.
  • โ€ขSafety concerns due to potential harmful chemicals like sodium tetraborate, causing illness in some cases.
  • โ€ขNot all necessary cups are included, requiring more materials for full enjoyment.

Bottom Line

While the SLIMYGLOOP Ultimate Slimy Laboratory offers an engaging and educational activity for kids, it falls short in clarity, ingredient sufficiency, and safety. If you're looking for a reliable and safe slime-making experience, consider purchasing individual ingredients separately to ensure both safety and success, or explore alternatives that provide clearer instructions and all necessary components for the full experience.
