Vous verrez de magnifiques cristaux rouges en cultivant les étonnants cristaux de 2.75 de large dans ce kit non toxique et sans danger pour les enfants. Comprend des instructions étape par étape.
We followed the simple instructions and the crystals grew into a beautiful, deep ruby red color that looks amazing in the sunlight. The kit was completely mess-free and the crystals formed exactly as promised. Definitely a fun and educational afternoon project.
My son was so excited watching the crystals form overnight—the step-by-step instructions made it super easy to follow. The deep ruby red color is just beautiful, and I love that it’s non-toxic so I don’t have to worry.
