Need a new toy for bath time? Boon Cogs could be that toy. These five unique gears suction to the bath walls, and when positioned correctly, water can be poured over the linked gears to create a water-powered chain. They don’t have to be used in the bath, it can be just as fun to stick to a window or table and spin a cog around.

The box contains five unique gears all made without BPA or PVC. Each gear can suction to the bath walls and be a great way to help teach cognitive skills and dexterity.

• Linked gears create a water-powered chain
