These unique building blocks are made of high-quality PU foam and look exactly like real, heavy boulders, but looks can be deceiving! They feel wonderfully soft, are completely safe, and so light that they even float on water. The Eduplay Foam Stacking Stones are spongy and provide a huge amount of fun. Children love playing with them and using them in all sorts of situations, both indoors and outdoors, such as for building forts or as accessories for their own small play worlds.

Creative Building and Gravity Play

The versatility of these rocks makes them an essential tool in the classroom or childcare setting. In combination with water channels or marble run systems, the stones can be strategically placed on the floor to create different height levels. In this way, children build their own gravity systems for balls, cars, or water flows. It stimulates not only technical insight but also fine motor skills and spatial awareness. Because the stones are waterproof, they are also perfect for use at a water table or outside in the sandbox.

Safety and Contents of the Set

Safety is paramount, especially for young discoverers from 1 year old. The stones have no sharp edges and are soft enough to cushion falls, yet firm enough to build stable towers. The set is very complete and contains 40 stones in three different sizes, allowing children to vary their constructions endlessly. Whether it is a wild water course or a prehistoric landscape for dinosaurs, these rocks bring every fantasy world to life.
