4M Crystal Growing Kit (Large)

Grow Real Crystals at Home — A Fascinating Science Experiment for Kids

The 4M Crystal Growing Kit (Large) lets kids set up a real crystal-growing experiment and watch crystals form over days. It's a genuine chemistry experience — kids mix the solution, set up the base, and check back daily as visible crystals slowly take shape. The large kit means bigger, more impressive results.

What's Inside the Kit

• Crystal growing solution
• Growing base and display stand
• Colour dyes to customise crystal colour
• Step-by-step instruction guide

Why Kids (and Parents) Love It

• Visibly dramatic results: Crystals grow larger and more impressive each day — kids love checking on their progress
• Real chemistry in action: Introduces supersaturation, crystallisation, and cause-and-effect thinking in a tangible way
• Teaches patience and observation: The waiting period is part of the lesson — great for kids who need to slow down and observe
• Display-worthy outcome: Finished crystals are genuinely beautiful and make great shelf or desk displays
• Large kit = bigger crystals: More solution means more impressive growth compared to standard-size kits

Good to Know Before You Buy

• Age: Best for ages 10+; adult supervision required for solution handling
• Adult involvement: Required for setup and handling the growing solution; kids take over for observation and monitoring
• Time: Crystal growth takes several days — this is a slow-reveal science project, not an instant result
• Fragile result: Finished crystals are delicate and can break if knocked or touched
• One-time use: The growing solution is used up in a single experiment
• No batteries required

Frequently Asked Questions

How long does it take for crystals to grow?

Visible growth typically begins within 24–48 hours, with the most impressive results forming over 3–7 days. The exact timing depends on room temperature and humidity — warmer, stable conditions tend to produce better results.

Are the chemicals safe for kids?

The kit is designed for home use, but adult supervision is required during setup and solution handling. Avoid contact with eyes and skin, and wash hands thoroughly after use. Keep away from young children and pets.

Can you do the experiment more than once?

The growing solution is a single-use consumable — once the experiment is complete, the solution is used up. The display stand is reusable if you purchase a refill kit separately.

What colour are the crystals?

The kit includes colour dyes so kids can choose their crystal colour. Results vary depending on the dye used and growing conditions.

Why is the large kit better than the standard size?

More solution means the crystals can grow larger and more dramatically. The large kit is better suited to kids who want a display-worthy result rather than a small tabletop experiment.
