Magic Tray / Tray

This product is a tray set applied with the principle of magnetism. I have checked the mistakes occurred in carrying foods of restaurant servers and attempted to think a way to complement the problems. When foods are carried, due to the law of gravity, the magnetic under the tray and the magnetic under the bowl are connected and magnetism arises. But, when the tray is put down, due to the spring inside the handle, a gap comes up upper side and bottom side, returns to the original state, so magnetism does not arise any more and the bowl can be detached easily.
