Transform bath time into an engineering adventure with COGS Water Gears. These clever suction-cup toys stick to your tub walls and whirl into action when water cascades over them. Watch as they mesh together in perfectly choreographed motion—no oil required, just pure aquatic magic. Pair them with PIPES or TUBES Bath Toys to build an elaborate water-powered contraption. Perfect for curious minds aged 12 months and up who love to splash, spin, and discover how things work.
