Since tonight is on Ouija boards, I'm just gonna say this now and copy paste if I need to. It's a tool, not a toy. The board itself is nothing more than wood. A spirit board can be made by marking the alphabet and yes/no on a kitchen table and using a water glass as a planchette. It's the operator that is dangerous. If the one using the tool does not use protections and properly manage the interface with spirit/entities, then a portal can be opened and left ajar. It's the person, not the equipment, that can be the danger.
