BathBlocks Tug Boat & Barge lets children build floating towns, bridges, towers and more in the bath. The tug boat and barge add action, fun and imaginative play to the floating playscapes. Sometimes the most educational toys are the simplest toys-- toys with lots of open-ended possibilities that encourage young minds to think, to create and to explore. The best of these toys provide progressive layers of challenge for children to discover as they grow. At their very best, these toys encourage exploration, reward discovery and empower our children. BathBlocksBlocks bring classic block play into a fun, fascinating, new, watery environment. The bath tub is the perfect places to create towers, tunnels, bridges and more. The "sticky" viscosity of water creates a helpful cling between blocks, and the movement, buoyancy and flow of water add an engaging twist to classic block play. BathBlocks empower children to create their vision and build STEM skills (Science, Technology, Engineering, Math) as they experiment with geometry, addition, subtraction, multiplication, division, balance, structure and cause-effect. BathBlocks have won Oppenheim Gold awards. BathBlocks are made from bacteria and mildew resistant EVA and contain no PVC or phthalates. WARNING: Age: 3+ years due to small parts.
