17 transparent blue acrylic solids – same shape but different volumes – unlock hands-on scientific learning. Coloured lids show where each solid opens. Water, sand or liquids pour in easily; volume and weight become direct, tactile experience. Ideal material for maths and science exploration.

How Children Play with It
Children fill the cube with water, then try the hemisphere. Which holds more? As they pour from one to another, hypotheses crumble and volume becomes tangible, not theoretical. Experimenting with sand or coloured beads, they watch how materials settle and shift. The transparent walls reveal hidden contents and train careful observation.
