Thermic Bottles (Tactile Sense)

This material includes 8 copper-plated bottles with lids, neatly arranged in a wooden box with 8 individual compartments. Each bottle is enclosed in a fabric bag. Designed to refine the child's thermic sense, this material builds upon the foundation established with thermic tablets. The bottles are filled with water at different temperatures, allowing the child to explore, pair, and grade variations in warmth and coolness.
