This is a funny fish feeder. It is composed of two modules, the food container and the handler, both with magnets. When you move the handler outside the tank wall, the food container on the other side of the tank wall will be attracted to move underwater by magnetic force. Meanwhile, food container has small gaps that can leak fish food slowly when dragged to move, attracting fishes move under your command.
