4M - Crystal Growing - Unicorn Crystal Terrarium

4M Unicorn Crystal Terrarium: Grow a Crystal Wonderland for Ages 10+

A little chemistry, a little patience and a unicorn to bring it all together. The 4M Unicorn Crystal Terrarium lets kids grow their own crystal over 4–7 days, then use it to create a miniature unicorn display. It brings hands-on science and creative decorating into one project, with something to watch as the days go by.

What's Inside

• White crystal compound and red colourant.
• 5 cm crystal base, stirring bowl and spoon.
• Miniature unicorn and flowers for decorating.
• Display case for the finished terrarium.
• Detailed instructions.

Why Kids (and Parents) Love It

• Science they can watch: follow the crystal's growth over several days rather than finishing everything in one sitting.
• A creative finishing touch: arrange the unicorn and flowers to turn the crystal-growing experiment into a miniature scene.
• A practical introduction to crystallisation: explore how crystals form through a hands-on chemistry activity.
• Something to display afterwards: the included case gives the finished creation a place to shine.

Good to Know Before You Buy

• Recommended for ages 10 and up. Follow the included instructions and any safety guidance on the packaging.
