Cristaux Géants

My son was absolutely mesmerized watching the crystals form on the little plaster shapes—the growth process is genuinely fascinating. The included mold makes it super easy to get started, and the final results are these beautiful, sparkling decorations he’s so proud of.

The plaster molds for the little shapes are really well-made, and the crystals cling to them beautifully once they start forming. My daughter kept checking the growing crystals every morning, and the whole thing kept her busy for a solid afternoon.

My kids were amazed watching the crystals form on the plaster shapes, and the kit includes everything you need without extra trips to the store. The crystals turned out really vibrant and colorful, even bigger than I expected for a home experiment.
